9. Setup – Targeting

In this lesson you will learn how to optimize the targeting of the antenna to track on or near a desired satellite (within +/-1

degree.

9.1. AUTO TRIM

The Auto Trim function will automatically calculate and set the required Azimuth and Elevation trim offset parameters

required to properly calibrate the antennas display to the mechanical angle of the antenna itself, while peaked ON

satellite.

Refer to “Optimizing Targeting” in the Setup section of this manual for further details on the parameters settings.

To enable this function, the Antenna MUST be actively tracking the satellite with positive Modem Lock and elevation

of the antenna must be less than 83 degrees and the MXP must NOT be set for Inclined Orbit Search. After locating

the satellite, with Tracking ON, wait at least 30 seconds before performing the AUTO TRIM feature, this will allow

sufficient time for the antenna to peak up on signal. It is equally important that you verify that the system is tracking

the CORRECT satellite (verify a RX lock indication on the satellite modem).

NOTE: The AUTO TRIM feature is NOT allowed unless all of these conditions are met:

• The antenna must be actively tracking a satellite (AGC above threshold) AND

• The antenna must have positive SAT ID (RX lock received from the Satellite

Modem) AND

• The elevation angle of the antenna must be LESS than 75 degrees AND

•

The antenna must NOT be set for Inclined Orbit Search.

1. To activate the Auto Trim function go to

the Reflector Configuration screen.

2. Click on the Auto Trim button.

This does not save these parameters to NVRAM, in

order to save to memory, click the Save button.
