2.12 Aligning ODUs with the Beeper
Perform the WinLink1000 ODU alignment using the beepers located
inside the ODUs. The beeper facility is not suitable for aligning the All
Indoor Units, AIND. To align an AIND system see Appendix D for
alternative alignment methods.
To speed up the installation time, alignment of a WinLink1000 ink can
be performed by two teams simultaneously, at site A and at site B.
Æ
To align the ODUs via ODU Beeper:
1. Verify that power is connected to the IDUs at both sites.
•
Warning
Do not stand in front of a live ODU.
2. The ODU starts beeping 20 seconds after power up, and continues
beeping until the ODUs are aligned, and the link is established.
3. Verify normal operation of the IDU by the LED indications on the
front panel. (See
Normal Indications .)
4. Coarsely align the site B ODU in the direction of the site A ODU.
5. Make an azimuth sweep of 180 degrees with the site A ODU. So
that the strongest signal from site B can be learnt.
6. Slowly turning the site A ODU back towards the position of Site B,
listen to the beeps until the best signal is reached. See
Figure 2-9
for the beeper signals.
