2.9 ODU Antenna Alignment
The ODU will provide the best link quality when its antenna is aligned in the
direction of the WiMAX base station. The optional SAU can be connected to the
ODU to provide status LED indications and assist with antenna alignment.
1 Remove the rubber sealing cover from the SAU port on the ODU.
2 Connect the SAU device to the SAU port. The PW (power) LED should turn on
to indicate that it is properly connected.
3 Point the ODU antenna in the general direction of the base station, then pan
the ODU back and forth while watching the link quality LEDs (see “SAU LED
Indicators” on page 18).
4 Find the point where the link quality is best and secure the ODU in that
position. Verify that the SAU’s WLNK LED is on, indicating that the unit is
synchronized with the base station.
5 Remove the SAU connection and replace the rubber sealing cover on the port.
To align the ODU antenna using the SAU, follow these steps:
NOTE
If all the SAU link quality LEDs are on, including LED 9 (red), the received signal strength is too
high. Move the ODU’s position so that only LEDs 1 to 8 are on.
