Figure 3-17 Beep Sequence For Antenna Alignment - Radwin WinLink 1000 User Manual

Connecting and Aligning ODUs / Antennas
When aligning the antennas, do not stand in front of a live antenna.
Warning
Provided that Site A detects the signal from Site B, the ODU starts beeping 20 sec-
onds after power up, and continues beeping until the ODUs are aligned, and the
installation is complete.
2. Verify normal operation of the IDU by the LED indications on the front panel (see
Table 3-2).
3. Direct the antenna of site B in the direction of the site A. This is simplified if a previ-
ous site survey has been completed and azimuths are known.
4. Make an azimuth sweep of 180 degrees with the site A ODU so that the strongest
signal from site B can be detected.
5. Slowly turning the site A ODU back towards the position of Site B, listen to the tone
until the best signal is reached. See the following figure for audible signal variations.

Note
6. Secure the site A ODU to the mast/wall.
7. At site B, adjust the ODU slowly whilst listening to the beeper sequence until the best
signal is attained.
8. Secure the site B ODU to the mast/wall.
9. Monitor the link quality for about 15 minutes to verify stability
