Channel selection
The PTP 600 series links are capable of transmitting and receiving on the same
channel or on different channels. In other words, the slave-master direction may use a
different channel from the master-slave direction. Independent selection of transmit
and receive frequencies can be useful in planned networks or for countering
interference.
When links operate in radar avoidance regions, each unit must monitor its transmit
channel for the presence of radar signals, and thus transmit and receive channels are
always identical.
