Installation
56
as a hub/switch (and auto-sensing MDI/MDIX cross over is employed), connection can be made
directly to the computer using a standard CAT 5 patch cable.
Before physical installation takes place the units to be installed should be set up as described in
the
"Install Pages". It is recommended that this procedure be carried out on the
bench before physical installation commences. Providing it is safe to do so, the installer should
take the process to the point where a radio link is established before proceeding to the installation
site.
NOTE:
It is possible that some units may not be accessed using the above default URL. This is
because these units may have been previously configured with IP addresses 10.10.10.11 (Master)
and 10.10.10.10 (Slave). Therefore, users must use the URL http://10.10.10.10/ and/or URL
http://10.10.10.11/ to configure the units. Please ensure that a computer with web browsing
capabilities is configured with an IP address of 10.10.10.n, where n is any value between 2 and 254
but excluding 10 and 11, to configure these units.

Aligning the PTP 500 Series Bridge ODUs
The following is a description of the steps taken to establish a radio link between the two units
forming the bridge and align the units for the best signal strength.
The PTP 500 Series Bridge uses audible tones during installation to assist the installer with
alignment. The installer should adjust the alignment of the ODU in both azimuth and elevation
until highest pitch tone is achieved
. The tones and their meanings are as follows:
State Name

Audio indications from the ODU
The term ‘wanted signal’ refers to that of the peer unit being installed.
In each of the states detailed above, the unit should be aligned to give the highest pitch tone. It
should be noted that if, when in the Synchronized or Registered state, the tone varies wildly, you
The pitch of the alignment tone is proportional to the received power of the wireless signals. The best results are
usually achieved by making small incremental movement in angular alignment.
