STEP 4. Verify appropriate software is loaded in the Remote ATM IDU and in accordance with
the System Configuration Document.
STEP 5. Verify the transmitter is disabled.
• Remote ATM IDU Set the rac_Commissioning_Complete register to No.
STEP 6. Load (Get and Set) appropriate registers in the IDU. Refer to the System Configuration
Document for appropriate frequencies, data rates, modulation schemes, etc. The icon
to the left of each of the configuration item's name should have a green plus symbol to
indicate successful loading of each configuration parameter.
10.2 Antenna Alignment
STEP 1. Enable the transmitter
• Set the rac_Commissioning_Complete register to No.
STEP 2. Connect the LSM to the Remote IDU controller card and set
odu_Antenna_Align_Enable to Enable.
STEP 3. Connect the Antenna Alignment Unit (AAU) to the Remote Terminal ODU auxiliary port
and prepare to align.
STEP 4. Loosen the appropriate bolts to allow the fine adjustment tuning of the antenna.
STEP 5. Azimuth and elevation adjustments should be made and confirmed with both visual
and electronic alignment with AAU of the Sector antenna. With correct course align-
ment, the demodulator will lock up to the sector transmit signal.
STEP 6. The person aligning the antenna at the remote site should now contact the person
located at the Remote IDU and confirm the remote site Demodulator has locked up to
the Sector Terminal. If it has not, course antenna alignment is incorrect and repeat
steps 4 and 5.
