Installation
70
For the ease of alignment, both Master and Slave units use the install tones in the same way
but with some small behavioral differences. This allows the installer to install the Slave unit
first and carry out the initial alignment with the Master unit if desired. However, due to the
behavioral differences of Master and Slave units, it is recommended that the Master unit is
installed first and the initial alignment carried out at the Slave unit.
There is a graphical installation screen available (Section 8.3.5 “Graphical Install”) using the
web interface that displays the state of the link during the alignment process (up = green,
down = red).
The following behavior should be noted:
State Name
Tone Description
State Description
Initialising
Slow beep
When first started up and from time to time, the Master
unit will carry out a band scan to determine which
channels are not in use. During this time, between 10 and
15 seconds, the Master unit will not transmit. During this
time the installation tone on the master unit will drop back
to the band scan state. Alignment of the unit should cease
during this time.
Radar CAC
Slow beep
The Master has to monitor the initially chosen channel for
60 seconds to make sure it is clear of radar signals before
transmitting. If a radar is detected during any of the
installation phases a further compulsory 60 seconds
channel scan will take place as the master unit attempts to
locate a new channel that is free of radar interference.
Searching
Slow broken
Searching for peer PTP 500.
Acquiring
Fast broken tone
Found a PTP 500. If it is the right one, it will move onto the
Registering state providing link conditions are OK,
otherwise, it will reverse to Searching.
Registering
Fast broken
Found right PTP 500 and is performing ranging function.
Link Up
Solid Tone
The ranging process is complete and the link is UP.
Alarm Fast
broken
dual
tone
A fatal error has occurred.
