Commissioning & Redeploying Your StarBand VSAT

This chapter will describe the process of setting up and connecting to the satellite for the first time and commissioning your satellite modem. A professional installer typically does these steps or guides you through the process:

        1. Assemble and point the satellite antenna/dish.
        2. Configure and connect the modem.
        3. Navigate CVACS, to check alignment and commission the modem.

Then, beginning with the topic Selecting a Suitable Camp Site, the rest of this chapter provides a how-to for each setup: hints, instructions, and checklists, for setting up and properly pointing (redeploying) your VSAT, every time you move to a new location. It contains guidelines for an optimal set up of a StarBand tripod-mounted antenna.

Remember that these are just guidelines. With experience, you may want to modify them, to better suit the particular conditions for each set up and your preferences. The main objective is to achieve a set up that is safe and stable, with a high quality signal.

Getting the Pointing Parameters and Confirming Polarity

There are a few things you should do to prepare to point to 121 W. First, you must use Point Dish, to get the pointing parameters (magnetic azimuth, elevation, and skew) that will be used.

Note if the polarity will change, from the current setup. For example, a feed arm will often ship, with polarity set for vertical, because it is easier to fit it in a box that way. However, all assignments on 121 W will need the feed arm set to horizontal. This will be discussed later.

You should also get a copy of the satellite parameters for your modem.

Using The Point Dish Utility

Point Dish will give you the angle of elevation, magnetic azimuth, and the skew/polarity settings for your current location. Shown above are the results for the Yuma, AZ Foothills.

Use the following steps to determine the pointing parameters, for your location:

Type 121 in the popup menu field, where the satellite is selected.
        1. Select and enter either the zip code or the longitude and latitude.
        2. Click Calculate . Write down the values returned.

Reconfiguring the BirDog

If you have a BirDog satellite meter, you will need to download a new configuration that includes the 121 W, Echostar 9 profiles. This is described in the BirDog appendix.

StarBand identifies the transmitted polarity, horizontal in the case of 121, to designate the polarity assignment. Since all assignments on 121 are horizontal, there will only be a KH profile, in the Named Services section.

If the transmit polarity is horizontal, then the receive polarity will be vertical. Most of the satellite industry identifies the received polarity, to designate assignment, so the appropriate “generic” profile will be KV.

You should add the following profiles to the configuration file:

The generic profiles are not related to specific services, but to the satellite itself. In the event that the StarBand network operations center (NOC) were offline because of bad weather, the generic profile would still allow you to “ find ” the satellite.

The BirDog web site provides many resources for BirDog satellite meter owners. More detailed photos and drawings of these steps are in the BirDog manual, which is available on the www.birdog.tv web site.

Step 1: Assembling and Pointing the Satellite Antenna

There are several tasks, in assembling and properly pointing your satellite antenna. Many of these steps must be done every time you move your dish. These tasks are only briefly covered here. They are discussed in detail later in this chapter, beginning with the topic Selecting a Suitable Camp Site .

A few steps are done only once, at the initial installation and commissioning. These steps are discussed here and in the Installer Training.

Erecting the Tripod and Plumbing the Mast

Use a compass to erect the tripod and antenna for the approximate direction of the magnetic azimuth, which was provided by Point Dish. Ensure the mast is plumb, by checking it with a level.

Changing the Polarity to Horizontal

If you currently have a vertical polarity assignment, it will be necessary to change the polarity setting from vertical to horizontal. This is something that typically occurs only during the initial installation.

The larger photo above illustrates the polarity, when set to vertical. In the blowup, you can see the “V” for vertical polarity, lined up with the zero. Note that the LNB is on the top, rather than out to one side.

The arrow indicates that the entire assembly should be rotated 90o ... although the arrow shows a clockwise rotation, it can be rotated counterclockwise instead. The “H” marks are on the shoulders next to the Phillips screws.

To see how it looks after rotating to the “H” position, proceed to the next page.

Observing Horizontal Polarity

For a horizontal setting, either of the H marks must be aligned with the zero, as shown above on the right.

Note that the LNB turns with the wave guide when setting polarity or when fine-tuning for cross-pol. This can be seen above, on the left. Note that the LNB is now off to one side, rather than on the top.

The LNB can be turned to either side of the wave guide for horizontal polarity. Both sides have alignment marks to align the zero.

Making the Settings on the Dish and Locating Echostar 9 - 121 W

The satellite parameters for the current location must be set, as follows:

The antenna will be aligned towards 121 W by monitoring the received signal with a signal strength meter, while the antenna is slowly moved in azimuth. If the StarBand satellite cannot be located, increase (or decrease) the elevation by one degree and again move the antenna through the azimuth. Continue increasing or decreasing the elevation in one degree increments, followed by a slow sweep through the azimuth, until the satellite is found. Once the 121 W satellite has been located, continue adjusting in azimuth and elevation, to obtain the maximum signal.

After the maximum received signal strength has been obtained, adjust for Adjacent Satellite Interference (ASI), by moving the reflector to the east slightly. These steps for setting up the antenna and peaking the signal are discussed in considerable detail later in this chapter. Right now, the focus is on the initial commissioning.

Step 2: Connecting & Configuring the Nova Satellite Modem

Connecting and configuring the Nova satellite modem is a multi-step process:

        1. Configure your PC’s Ethernet connection to use the IP address 192.168.1.2 , with a subnet mask of 255.255.255.0 .
        2. Connect an Ethernet crossover cable from your PC to the Nova. In Internet Explorer, type 192.168.1.1 in the address bar, to connect to your modem.
        3. Click on Installer and log in with username = inst and password = $Sat2598$ .
        4. Click on Setup from file and upload the configuration file.
        5. Click on Setup and enter the VSAT ID .
        6. Power down the modem.
        7. Connect the modem to the satellite antenna via the IFL cables.

We will now look at these steps in more detail.

Substeps 1 & 2 – Assigning an IP Address and Connecting to the Nova Modem

In order to configure your modem, you must first connect to it, as described by the first two substeps.

        1. First, you need to give your PC’s Ethernet connection a static IP address of 192.168.1.2 . The modem will use the IP address of 192.168.1.1 . You cannot communicate with the modem when it is offline without assigning a static IP address to your PC. When your modem is online, you can use automatic IP addressing. For details on how to configure a static IP address, please see Appendix C, Configuring IP Addressing .
        2. Once you have assigned the static IP address, plug in an Ethernet crossover cable, connecting your PC to the Nova modem. Then, type the IP address of the modem, 192.168.1.1 , in the address bar of your web browser, as shown above and hit the <Enter> key.

    Note: Make sure you do not have a browser proxy set. This will prevent you from connecting to your modem.

Substep 3 – Logging in as Installer

When you connect to the modem, you will see the SkyManage Status page, in the Status section. The Status page above is shown as it will appear when you have four lights ON solid, on the modem, and you are online.

The three sections have links across the top and include Status , Tools , and Installer . The Tools section isn’t always available.

Only those functions relevant for the reconfiguration process are discussed here. Functions that aren’t discussed in this chapter will be covered in the next chapter, Help & Troubleshooting Information .

Click on Installer and log in with username = inst and a password = $Sat2598$ .

You will then be shown the Setup page, which is shown later.

Substep 4 – Uploading the General Configuration

Most often, there will be a configuration file available on the training web site, which contains the standard parameters for all devices on a particular service plan and assigned to a given transponder (cluster). This greatly simplifies the task of configuring the modem, since it will correctly configure all but the VSAT ID setting, which must be unique for each site.

When the installer page is displayed, click on Setup from file (A) . The page shown above will then be displayed.

Then click on Browse (B) and navigate to where the configuration file has been saved and click Open . Finally, click Load (C) , to upload the configuration file.

You will be presented with a Windows dialog asking “ Are you sure? (D) When you click OK , the parameters will be loaded and you should receive a Succeeded (E) message. Click OK to complete the process.

Uploading the configuration is illustrated above.

Next, you must go back to the Installer Setup page and change the VSAT ID to your unique number, as shown on the next page.

Substeps 5 & 6 – Configuring the VSAT ID and Connecting the Coaxial Cables

You now need to configure your unique VSAT ID and then power down the modem, so you can go on to connect the coaxial cables.

        1. Click on Setup on the left and then enter the unique VSAT ID, as shown above. You do not have to type leading zeros. After you have entered the VSAT ID, click Submit , to save the change. As noted earlier for configuring with a file, you will be presented with the Are you sure? and Succeeded messages, which must be acknowledged by clicking OK .

        Occasionally, there is no available configuration file and everything must be manually configured on this page. In this case, you will need a list of the satellite parameters, as illustrated on the page entitled, Step 2 - Configuring and Connecting a Nova Satellite Modem . Only the General and Modulation and Coding sections on the manual Setup page are normally changed. The other sections will use the defaults.

        1. Power down the modem. You are ready to connect it to the antenna via the coaxial (IFL) cables, as discussed next. Once you have connected the cables and powered on the modem, you can watch the progress of the commissioning on the SkyManage Status pages.

Substep 7 – Connecting the Modem to the Antenna

You must now connect the coaxial cables between the antenna and the StarBand satellite modem. The illustration above shows the location of all cables, for the StarBand Nova modem. Always make sure the modem is powered OFF, before you connect or disconnect the coaxial cables.

If the Rx light does not come on, you are likely not locked onto the correct satellite. Recheck all of your settings on the dish.

Monitoring the Progress of the Download

To monitor the progress, just click on the Status link at the top of the SkyManage page and then click on Telemetry on the left.

The bottom bar shown above is the download status bar. It is only visible when a download is in progress. The download normally takes between five and 10 minutes. When the download reaches 100%, click on Status on the left and you will see the page shown above with all of the green check marks.

When you first view this page, not all of the green checks will be present. There is a correspondence between some of these green checks and the status lights on the modem. For example, the Rx light will be on, when Outbound - Locked has a green check. Likewise, the SYNC light will be on, when the Sync - Synchronized green check is present.

When all four of the modem lights are on and all of the green checks are present, it is time for you to check the alignment and finish commissioning the modem.

The modem should start cycling. It will take several minutes and the modem may power cycle several times before it finally gets all four lights on.

If the ONLINE light doesn’t come on, even after waiting at least 30 minutes, power cycle the modem. If it still doesn’t come on, technical support may be needed.

Step 3: Checking Alignment & Commissioning the Modem

CVACS is used to validate and fine-tune the co-pol, cross-pol, and ASI values and to get a confirmation number, which is the last task that must be performed. The CVACS menu structure is shown in the figure above. Once this is complete, you will be able to go online and register for your StarBand two-way satellite service and begin using it, to browse the Internet.

Checking Alignment with CVACS

After all of the installation steps have been completed, CVACS is called. The Antenna Alignment Main Menu option, Check Alignment submenu option is used first, to obtain the co-pol, cross-pol, and ASI values. If the CVACS criteria is met, you can go on to the next step, getting the Confirmation number, which is only ever done once.

If the site does not meet the criteria, finer adjustments to the antenna pointing will be required in the azimuth, elevation, and/or polarization axes. The co-pol or cross-pol (or both) will be adjusted with the corresponding Alignment Menu submenu options. There is also an ASI adjustment option, but it is not yet functional. A web-based interface for checking the alignment is under development.

How to adjust your setup when it doesn’t meet the criteria is discussed in great detail later in this chapter.

Here is an overview of the adjustment process:

Obtaining the Confirmation Number.

The commissioning process is completed by obtaining the confirmation number. CVACS will again measure the co-pol, cross-pol, and ASI values, to verify the antenna is within the specified limits.

The values will be recited, along with an indication of whether or not the setup meets the criteria. If any of the measured values do not meet the criteria, the message will tell you which one does NOT meet criteria. You will then need to adjust further, until your setup meets the criteria.

When your setup meets the criteria, a confirmation number is generated. You should make a note of this number. It will be used in the next step, registering as a StarBand member.

Note: You should never again request a confirmation number. Although it doesn’t usually hurt anything, it can cause the CVACS Notification Number to become invalid in CVACS. You then have to ask your dealer for another one.

StarBand Registration

When you connect to your modem the first time after it has been commissioned, you will need to register for your StarBand.net member account.

When you open the web browser, your browser should be automatically redirected to the page shown above. Just click on the button to begin.

If you don’t see this page, type http://portal.starband.net/registration to begin the registration process.

Confirmation Page

You should then see the page shown above. If you do, enter your confirmation number and click Continue .

If you don’t have the confirmation number or if CVACS doesn’t recognize the number, you will have to wait about 30 minutes. Whether you enter a confirmation number or wait 30 minutes, you should see the StarBand member service agreement after you click Continue .

Accepting the StarBand Member Agreement

After you “Click here to get started” and possibly enter your confirmation number, you should see the StarBand member agreement. Among other things, the service agreement states your monthly service fee and length of the contract. It also lists exactly what your membership includes.

Just scroll down to the bottom and click “ I accept ” to continue.

Setting Up Your StarBand.net Member Account

You should choose a member name to be used for your primary account. Remember that you get up to 10 email accounts, but only one is your primary account.

On this page you should enter the following information:

Selecting a Suitable Camp Site – Every Time You Move

We will now start looking at the process of setting up every time you move. If possible, use the Point Dish utility to obtain the azimuth setting for your next destination, before you leave for it. This will help you pick your site upon arrival.

Using a compass, select a site that has an ample amount of clear horizon (about 10-15 degrees east and west of the required azimuth setting), as shown in the graphic above. Make sure the tripod location on the site is in an area away from the foot traffic.

If there is no clear horizon, remember that the signal to and from the satellite comes in and goes out, at a relatively steep angle. An object like a building, another RV, or tree can block the horizon, but a good signal can still be obtained.

Remember that, as you travel, the required elevation adjustment will also change. As this adjustment becomes lower to the horizon, more objects will impede the signal.

The Point Dish Utility

Use the following steps, for using the Point Dish utility, to determine the angle of elevation, azimuth, and skew/polarity settings for your location:

Enter 121 or select it from the popup satellite menu.
        1. Select and enter either the zip code or the longitude and latitude.
        2. Click on Calculate.

Setting up the Tripod and Offset Adapter

Erect your tripod and attach the offset adapter. Please see Appendix D, Assembling the Offset Adapter , for more detail.

It is important to correctly orient the tripod legs and offset adapter, to ensure a stable setup. It is recommended that the front leg of the tripod be aligned with the azimuth direction, as shown.

Use your compass to align the front leg with the desired azimuth. The offset adapter will also be aligned with the azimuth, but extending in the opposite direction, midway between the two rear legs. Once aligned, tighten the adapter to the tripod. The figures above show the top and side views of the recommended orientation of the tripod and mounted offset adapter.

Setting up the Tripod and Offset Adapter – The Wrong Way!

As stated earlier, it is very important to correctly orient the tripod legs and offset adapter, to ensure a stable and successful setup. This page shows what you should NOT DO!

The photos above show the top and side views of an incorrectly oriented tripod and mounted offset adapter. You can see that neither the rear tripod leg nor the offset adapter are aligned with the azimuth direction.

Additionally, the arrangement shown above is not balanced. It would not be a safe setup. The tripod could easily fall over in the wind, because it is not stable.

Plumbing the Mast, Assembling, & Adjusting the Antenna

Follow these steps, for an easy setup:

Get Ready and Plumb the Mast
        1. Install the Reflector/AZ/EL Skew Cap Mount
        2. Adjust the Elevation
        3. Adjust the Skew/Polarization Setting
        4. Install the Rx-Tx Feed Assembly
        5. Re-check the Plumb
        6. Add the Ballast

Step 1: Getting Ready and Plumbing the Mast — Using the Built-in Bubble T-Level

A bubble T-level attached to the offset adapter will help make your setup even easier. The T-level was calibrated to a plumb mast when it was attached. Simply adjust your tripod legs, until the T-level shows “Level” in both directions.

Step 1: Getting Ready and Plumbing the Mast — Using a Mast Level

Make sure the tripod legs are firmly planted in the ground, to hold it in place. On hard surfaces, you will need to keep the legs from spreading with chains or other restraint.

Before installing the antenna, plumb the mast (vertical tube) of the offset adapter using a mast level, as shown above. Check along the azimuth angle and at 90 degrees to it. At this point it does not have to be exact, but make it close to plumb. Later you will make adjustments, to ensure a plumb mast in the final set up.

Attaching and Calibrating a Bubble T-Level

Here are the steps to follow, to attach and calibrate a T-level to your mast adapter:

Use the method described above, to plumb the mast of your offset adapter.
        1. Use Clear Liquid Nails or something similar, to attach the bubble level to the center channel of the adapter.
        2. To calibrate the level, build up the surface where the level attaches, so that with your mast already plumb, the bubble level shows “Level” in both directions.
        3. Allow this to dry overnight.

Step 2: Installing the Reflector/AZ/EL Skew Cap Mount

Install just the reflector/AZ/EL Skew Cap Mount assembly onto the mast, at this time. Make sure the assembly tab aligns with the notch in the adapter, if the notch is present. This is shown in the figure above, on the left. The Rx-Tx feed assembly will be added later.

Tighten the clamp bolts on the mount assembly, as indicated in the center above.

Use the compass to align the reflector/AZ/EL skew cap mount, mast, and the front tripod leg to the azimuth, as illustrated in the graphic, on the right.

Step 3: Adjusting the Elevation

Use the following steps to adjust the angle of elevation, to the recommended value plus one to two degrees. Refer to the figure above, for the location of each adjustment:

        1. Loosen the elevation lock bolts one-half turn. These bolts are located in the curved slot on each side of the AZ/EL Skew Cap Mount.
        2. Loosen the pivot bolts a quarter turn. The pivot bolts are also located on each side of the AZ/EL Skew Cap Mount.
        3. Now, turn the elevation adjustment bolt clockwise, to decrease elevation. Turn the bolt counterclockwise, to increase elevation.
        4. Align the edge of the bracket with the appropriate elevation mark on the AZ/EL housing.

    Note: Remember to add 1 to 2 degrees, to the recommended elevation setting provided by the Point Dish tool.

Step 4: Adjusting the Skew or Polarization Setting

The skew or polarization is probably the most critical setting. It is this setting that should be validated via the CVACS cross-pol test, after each move. In this step, you will adjust the setting, per the Skew/Polarization value provided by the Point Dish utility.

Later, you will use CVACS to check the alignment. If your settings do not meet the criteria, you will fine-tune the skew setting, with the help of CVACS.

Complete the following steps, to set the skew. Refer to the figure above, for the location of these adjustments:

        1. Loosen the four skew locking bolts, until they are just finger-tight. These bolts are located on the AZ/EL skew cap mount, where the mount is attached to the antenna.
        2. Rotate the AZ/EL skew cap mount, to align the indicator mark with the correct number on the skew scale. The scale is marked in two-degree increments.
        3. Tighten the skew locking bolts. Don't over tighten.

You may need to fine-tune this setting later.

Step 5: Installing the Rx-Tx Feed Assembly

Some two-way satellite users prefer to perform the settings discussed in the earlier steps at a table, and then mount the dish. The approach recommended here was chosen, because it is easier to make the adjustments, with the dish mounted on the tripod. In either case, it is recommended that the settings be made and the dish mounted, before the Rx-Tx feed assembly is attached.

Use the following steps to install the Rx-Tx feed assembly. Refer to the figure above, for details:

        1. Remove the hardware that attaches the feed support arm to the dish.
        2. Insert the feed support arm into the notch on the bottom of the reflector.
        3. Secure the feed support arm to the reflector, with the hardware that you removed in Substep 1.
        4. Don't over tighten.

    Note: The figure above shows a Phase III setup on the left and Phase II on the right.

Step 6: Re-checking the Plumb

A well-plumbed mast will make your job easy! A well-plumbed mast is probably the single biggest factor, for setups that go smoothly, versus those that are long, tedious, and frustrating. If your mast is properly plumbed, when you have optimized your receive signal, you should pass cross-pol easily.

As shown in the figure above, you should re-check the plumb, using either an attached bubble T-level or a mast level:

This is an important step, because the tripod legs can flex or shift slightly after the antenna adjustments and with the addition of the weight of the entire antenna assembly.

Once the final plumbing of the assembly is complete, make sure the tripod legs are tight.

You are now ready to add ballast to your completed antenna assembly.

Step 7: Adding the Ballast

Once you have fully assembled and plumbed your antenna setup, it is VERY important to add appropriate ballast to the tripod and antenna. Although the installation seems very stable, it can be upset by strong winds. Think of the antenna as a big sail - a strong wind could easily blow the entire assembly over and damage the equipment.

It is recommended that you add a minimum of 50 lbs of ballast, to the antenna tripod. Examples of suitable ballast include a 5-gallon bucket, filled with water or rocks, or two 25-pound barbell weights, as shown in the figure above.

Make sure that adding the ballast has not affected the plumb of the system.

Preparing for Inclement Weather

If you are going to leave the antenna assembly unattended in an area prone to sudden server weather, or if there are severe weather warnings issued, it is recommended that you remove the Rx-Tx feed assembly and the reflector/AZ/EL Skew Cap Mount assembly, separately, from the tripod adapter. Try not to upset the plumbed mast and tripod, so when you remount them, realignment will be more easily achieved.

In general, always use common sense in evaluating your local weather conditions and the deployment of your StarBand VSAT.

What If I Don’t Add Enough Ballast?

The photo above illustrates what can happen to your satellite dish, if the wind kicks up and your tripod-mount dish is not properly ballasted. It typically breaks at the point where the feed-assembly arm is attached to the dish.

    Note: See Appendix H, Tips for Safe & Stable Tripod Setups , for some guidelines for a stable tripod setup.

Locating the Satellite and Peaking the Receive Signal

Now, you will use a satellite meter like the Digisat III Pro or the BirDog, to peak the received (outgoing) signal:

        1. Attach the meter
        2. Locate the correct satellite
        3. Peak the received signal
        4. Attach the IFL (coaxial) cables

Step 1: Attaching the Meter

This step assumes a fully charged BirDog or Digisat III satellite meter. When using a Digisat III in self-powered mode, use the 13V setting, to save battery power.

Attach an RG-6 cable from the Rx point (LNB) on the Rx-Tx Feed Assembly, to the connector marked LNB on a Digisat III or to the connector marked Input on a BirDog.

Cable lengths and meter position shown are for illustration purposes only. Actual cable length will be for optimum placement of the meter, for visibility.

Step 2: Locating Echostar 9 at 121 W

Locate the correct satellite, as follows:

The Digisat meter will only locate an unidentified signal - you will not know if it is the correct satellite until you have removed the meter, connected the cables and powered on the modem. If you have a BirDog meter, it will positively identify the correct satellite only.

Searching for Echostar 9 with a Digisat III Pro Meter

The illustration at the bottom left shows the Digisat III Pro, when the correct satellite has not yet been located. The signal strength is weak.

As you rotate from west to east, you will see the number grow significantly larger … the peak that occurs as you move into a satellite’s beam is very obvious! The first large peak is Galaxy 27, at 129 W.

If you keep rotating, past the azimuth direction, you will see another VERY SIGNICANT increase. If you see this second LARGE peak, you have gone too far … you have gone just past 121! We think (but haven't verified) this second large peak is the 119 W satellite.

If you watch the Digisat very carefully as you slowly rotate the dish, you will notice a much smaller increase that gets a little bigger JUST BEFORE the second LARGE peak. The signal you are seeking is at this position JUST BEFORE the second LARGE peak.

If you enable the audible tone, you will be able to hear the different tones, with the two LARGE PEAKS sounding about the same and the Echostar 9 peak having a distinctly different tone.

These peaks are graphically depicted in the diagram at the upper left.

Searching for Echostar 9 with a BirDog Meter

On the right is the BirDog, still Searching for the correct satellite.

Step 3: Peaking the Received Signal

Once the satellite is found, peak the signal by making minor adjustments to the antenna:

Step 4: Attaching the IFL Cables

You now need to remove the meter and attach the cables from the modem to the Rx-Tx Feed Assembly.

Attaching the Cables
        • Make sure the modem is turned OFF .
        • Attach the transmit (Tx) and receive (Rx) IFL cables:
          • Attach the Tx or transmit cable from the connector marked RF-OUT on the modem, to the Tx connection point, on the Rx-Tx feed assembly.
          • Attach the Rx or receive cable, from the connector on the modem marked RF-IN , to the LNB.
        • Turn on the modem.

    Note: Remember that the Digisat III Pro does not guarantee that you are receiving the correct satellite signal. You must attach the coaxial cables and turn on the modem, to verify that you have located and peaked the proper satellite signal. The Rx light on the modem should illuminate, as soon as the modem finishes its power-on cycling.

Checking Alignment and Adjusting the Setup Using CVACS

After you have completed your setup, you will need to dial the CVACS telephone number and validate your setup. Before you call, wait 10 to 15 minutes after connecting all cables and powering on the modem, to make sure that any downloads which may be in progress can complete first.

Use the following procedure, to call CVACS and check the alignment. The graphic above and on the CVACS side of the laminated setup card illustrate the process:

        1. Make sure all modem lights are on, except for the Tx light. If this is not true, shut down the modem and then restart it.
        2. Dial the CVACS telephone number and when the automatic response system first answers and begins the introduction, hit the number 1 key, for CVACS.
        3. When prompted, hit the number 1 key, for English.
        4. Respond to the CVACS prompts, to enter your User ID (installer number), your password (passcode), and your Notification (Z8) or Equipment Record Number (ERN). Hit the pound sign ( # ) after each entry.
        5. After you have reached the CVACS main menu, Select Option 2: Align the Antenna, Suboption 1: Check Alignment .

Criteria Met – Exiting CVACS

If the recited co-pol, cross-pol, and ASI West co-pol values all meet the criteria, you are almost finished. Just back out of the CVACS menu structure by selecting Option 6 : Return to the Main Install Menu , and Option 4: Return Later . Failure to do this can cause the CON/ON-LINE light on a StarBand 360 or 48x modem to remain out and you may not be able to go online until you contact technical support. On a StarBand Nova modem, the ON-LINE light will often stay out after an alignment check. Power cycling the modem will put it back online.

Criteria Not Met – Fine-tuning Co-pol and/or Cross-pol or Adjusting for ASI

If the response is Criteria Not Met, for the co-pol, cross-pol, or ASI values, then further adjustment to your setup is needed, as detailed below.

Co-pol < 23.0
      1. If the co-pol value is below 23.0, you must readjust for maximum signal (azimuth and elevation settings), as described previously. Navigate to the CVACS main menu Option 2: Align the Antenna, Suboption 3: Co-pol . Make a minor adjustment to either the azimuth or the elevation and then wait for new values from CVACS, before you again adjust it. Hit the # to exit this mode.
Cross-pol > 3.0
      1. If the cross-pol value is above 3.0, then you must fine-tune the skew. Navigate to the CVACS main menu and select Option 2: Align the Antenna, Suboption 4: Cross-pol . Make a minor adjustment to the skew by either increasing or reducing the skew value and wait for new values from CVACS, before you again adjust it. It will be very apparent if you have moved the skew in the wrong direction - the number will get larger, instead of smaller. Continue adjusting until the cross-pol value is below 3.0 and as small as possible. More information about this step is in See Fine-tuning the Polarization/Skew Setting, on the next page. Hit # to exit this mode.
Co-pol < 23.0 and Cross-pol > 3.0
      1. If both the co-pol and cross-pol need adjustment, navigate to the CVACS main menu and select Option 2: Align the Antenna, Suboption 2: Continuous Alignment . This option will alternate co-pol and cross-pol tests, so you can adjust both, as described above. You may never need this option. Hit the # to exit this mode.
ASI > 5.0
      1. The option for adjusting ASI is not yet available in CVACS. If you select Option 2: Align the Antenna, Suboption 5: ASI , you will receive a System Error message. To adjust for ASI, just move the dish to the east slightly and possibly down, as described earlier.
Fine-tuning the Polarization/Skew Setting

The photos above show the four screws that must be loosened, to fine-tune the polarity setting. If you have one of the MobileInternetSatellite.com polarity adjustment kits, you will use the T-handled allen wrench included with the kit to do this. Once the screws are loose, carefully and slowly move the polarizer, as described on the previous page. If adjusting cross-pol won't get number below 3.0, check the looseness of the donut clamps. If you loosen the four screws too much, the polarizer can become wobbly and cross-pol values become very erratic.

Calibrating the LNB to the Skew Scale

If the LNB is calibrated to the skew scale, it is much more likely that criteria will be met on the first alignment check. Here is a method for doing this:

        1. Take your dish and set the skew to 90, with the polarity set to horizontal or vertical, depending on your assignment.
        2. Set the elevation to 10. The feed arm will be parallel to the ground. You should be able to rest a level on the LNB and it will be perfectly horizontal or vertical.
        3. You will notice that there is quite a bit of slop in the polarizer. The donut clamps can move back and forth, by one or two degrees or more, in each direction. “Calibrating” your polarizer as described here sets the LNB to the skew scale. After this, setting the skew should be more accurate.

Checking Alignment Again

Once you have made the adjustments for any values that didn’t meet the criteria, return to Option 2: Align the Antenna, Suboption 1: Check Alignment . Your setup should now meet the criteria. If this is the case, remember to back out of the CVACS menu structure, by selecting Option 6 : Return to the Main Install Menu , and Option 4: Return Later .

If the criteria isn’t met, you will need to repeat Step 6.

Setup Checklist and RovingInternet.com Setup Guide

After you’ve completed only two or three setups, you shouldn’t need more than your laminated Setup Card, to successfully set up your satellite dish and verify its operation. The Setup Checklist side of the Setup Card is shown in the figure above. Using CVACS is on the other side of the card.

The table below summarizes the alignment criteria. A summary of how to adjust for out-of-criteria values is provided on the next page.

Summarizing the Alignment Criteria and How to Adjust to Meet It

The table on the previous page and the following information is from the RovingInternet StarBand Aiming Guide .

Understanding the Importance of the Alignment Criteria

Cross-pol and ASI are monitored by the NOC. A high cross-pol indicates a signal that is interfering with others on the satellite. A high ASI is interference with an adjacent satellite. If either condition is detected by the NOC, the user will be sent an email to correct the problem within 24 hours. If the problem is then not corrected, the user's account will be shut down, until it has been corrected.

Adjusting for the Lowest Cross-pol

First, adjust the azimuth and elevation until you get the highest co-pol and lowest cross-pol numbers, as measured by CVACS. If the cross-pol is still high after that, adjust the polarizer until you get the cross-pol as low as possible. If, after minimizing with the polarizer, it is still high, readjust azimuth and elevation specifically for a lower cross pol number.

Adjusting for the Lowest ASI

Using CVACS, adjust for the lowest possible ASI number. CVACS will read ASI as “ASI West, Co-pol X.X”. The “West” indicates that your ASI is being measured west of your assigned satellite. You must move your aim east, to lower the interference on satellites to the west, where the closest satellite is located.

When doing initial aiming with a digital meter such as a Birdog or Digisat, after adjusting for the highest signal with azimuth and elevation adjustments, move your azimuth aim a little west, dropping the signal reading by one or two points on the digital scale (lower scale on Birdog when “Found” indication is present). You may need to also lower the elevation, to achieve the lowest possible ASI value.

We have found that using this method will often give you passing ASI numbers without further adjustment. Fine tuning for the best numbers possible is always the best practice. Make tiny adjustments and continue to monitor your cross-pol and co-pol.

Defining Signal Quality and Why It is Important, Too

If your signal gets to the 4.8-5.2 range, you will likely lose service. If you have a signal quality of 5.5 and a rainstorm comes in that causes a 2.5 dB drop in signal quality, you will go offline. However, if you are starting with a signal quality of 8.0, this same 2.5 dB loss will leave you at 5.5, which is marginal, but you will probably still be online.

Signal quality will be directly proportional to the peaked signal on your BirDog meter, so always make sure that your signal is at the highest possible value.

Cross-pol and ASI trump signal quality, but always start fine tuning with the best signal possible!

Transporting Your System

Almost as important as proper setup is the teardown and stowing of your satellite equipment for travel. Proper care of your equipment will help it to provide years of trouble-free service for you.

It is recommended that the following steps be taken, when transporting the system:

        1. Remove all outside cables, except the shorter “ pig-tail ” cables attached to the Rx-Tx feed assembly. Leave these connected.
        2. Remove the Rx-Tx feed assembly from the reflector/AZ/EL Skew Cap Mount assembly.
        3. Remove the reflector/AZ/EL Skew Cap Mount assembly from the tripod adapter.
        4. Remove the offset adapter from the tripod. (optional)
        5. Collapse the tripod legs.
        6. Store all the components in an appropriate fashion.

There are different approaches for storing the equipment. For those with a large basement area, most or all of the equipment, can be stored there. Some mobile users store the dish and Rx-Tx feed assembly separately. As another example, these two items could be stored on the bed, during travel.
