Aligning Antennas with the Beeper
Perform the antenna alignment using the ODU’s audible tone. The tone
is not suitable for aligning the All Indoor Units (AIND). To align an
AIND system, see
AIND Alignment.
To speed up the installation time, alignment of a WinLink™ 1000
system should be performed by two teams simultaneously, at site
A and at site B.
Æ To align the ODUs using the alignment tone:
1. Verify that power is connected to the IDUs at both sites.
Do not stand in front of a live ODU.
Provided that Site A detects the signal from Site B, the ODU starts
beeping 20 seconds 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 IDU Front Panel Indicators.
3. Direct the antenna of site B in the direction of the site A. This is
simplified if a previous 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.
