Calibration - Winegard 2-WAY SATELLITE INTERNET SYSTEM Product Manual

4. Press the "Update Now" button to begin the update. NOTE: If the dish is not
deployed, the system will automatically search for files on the USB drive instead
of the online download area.
5. The system will automatically search the root directory of the attached USB
drive and if the software listed above is found, the system will automatically
update the software with the version on the USB drive.
6. The software will show a progress bar and indicate when it is finished updating.
Do not go to step 7 until this finished status is displayed.
7. Cycle the power on the controller when the system returns to the Main Menu.
8. Check the version of the software using one of the procedures described in page
54 to ensure the correct version has been loaded.

8.4 - Calibration

There are several different systems that require calibration. The first group of
calibration procedures are factory set calibrations and will only be required if the
Outdoor Unit (ODU) or the Azimuth Position Sensor are replaced.
These procedures include calibration of the azimuth home position, calibration of the
skew position, or calibration of the Vehicle Attitude Board (pitch and roll).
The second calibration procedure involves systems that may require periodic
calibration. These include setting the antenna system's home position and calibration of
the on-board compass. Both of these procedures can be accomplished using either the
USB keyboard or the Indoor Unit (IDU) in normal operation.
8.4.1 - Calibration of the Skew Home Position (zero degree skew)
This procedure should be performed if the antenna does not return to the zero degree
skew position during motor calibration. This procedure requires a USB keyboard (or
alternate method). The system must be in debug mode as described earlier in this
document.
It is very important that the antenna elevation is high enough that antenna can skew
freely. When the skew motor is calibrated, it will rotate the skew all of the way in one
direction and then return the skew to zero degrees. If the system does not return to
zero degrees, it will be necessary to adjust the maximum skew angle in the ODU
memory.
1. The IDU screen should display "trk>".
2. Hold down the control key (ctrl), press "t", release both keys and then press enter.
a. The IDU screen should change to the capital "TRK>" prompt.
3. At the "TRK>" prompt type "home" and press enter.
a. The IDU screen should now display the 'HOME>" prompt.
4. At the "HOME>" prompt type "h 2" and press enter.
a. The command will calibrate the skew motor.
b. If the skew does not return to the zero degree position, then the maximum
skew angle will need to be changed.
