This procedure should be performed if the LNB arm does not line up with the stow

position bracket. 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 the LNB arm will

clear all obstacles.

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. Type “dc” and press enter.

a. The IDU prompt should change to “DC>”

4. Type “p 1 1500” and press enter.

a. The LNB arm should lift off of the stow tray.

b. Verify that the LNB arm will not hit any obstacles when the azimuth motor is

engaged.

c. If the LNB arm must be raised farther, type “p 1 1600”. Continue increasing the

position value until the LNB arm is at a safe elevation.

5. Center the azimuth.

a. Visually inspect the front of the antenna assembly to see if the unit is aligned

in the middle of the stow tray.

b. If the unit is aligned, skip to step 6.

c. At the “DC>” prompt, type “p 0 -500” and press enter. This will rotate the

azimuth motor clockwise past the magnetic sensor.

d. At the “DC>” prompt, enter the command “p 0 +100” and press enter. This will

rotate the azimuth counterclockwise back towards the center of the tray.

e. Continue to rotate the azimuth towards the center. It may be necessary to

decrease the amount of travel by entering values less than 100 in order to stop

at exactly the center position.

f. The system must be brought to the center position from this direction. If the

system overshoots the center position, it will be necessary to start back at step

5c above.

6. Calibrate the center (0) position.

a. From the “DC>” prompt, type “calib” and press enter.

b. Then type “y” when asked if the azimuth is at 0.

c. The azimuth should move in both directions. It may not return to the centered

position.

7. From the “DC>” menu, type “home” and press enter.

a. The IDU screen should change to the “HOME>” prompt.

8. At the “HOME>” prompt type “h” and press enter.

a. The system should go through a motor calibration.

b. Verify that when the system stows it is centered on the stow tray.

c. If the system is not centered, it will be necessary to return to step 3 and repeat

this procedure.
