Establishing a radio link
This section describes how to establish a radio link between the two units forming the
bridge and align the units for the best signal strength.
Before performing these tasks, connect the PIDU Plus to the network, power up the
unit and open the web interface. For more information, refer to:
• Powering up and connecting the PIDU Plus on pa
ge 5-3.
• Opening the web interface on
page 5-4.
Using the ODU installation tones
The PTP 600 ODU emits audible tones during installation to assist with alignment. The
pitch of the alignment tone is proportional to the received power of the wireless
signals. Adjust the alignment of the unit in both azimuth and elevation until the
highest pitch tone is achieved. The tones and their meanings are described in Table
5-5. In each of t
he states detailed in the table, align the unit to give the highest pitch
tone.
