7.3.3 CN7 RX Input
This is a BNC connector used as the RX RF input.
7.3.4 CN8 TX Output
This is an N type connector used as the TX RF power output.
7.3.5 CN9 RJ45
This connector may optionally be fitted. The function depends upon which
option board is fitted. A standard option is the isolated line I/O and this
connector is used for this function when this option is fitted. See Options
section for connection details.
A rectangular knock out section in the chassis provides for mounting of the
connector should it be required.
7.3.6 CN5 DC Power Input
DC power is connected to the transceiver through this connector. The
transceiver is fitted with a 3-pin male connector. For 50W transceivers pins 2
and 3 are used for the 12V DC pin 1 is unused. The power lead to the
transceiver should be made from a gauge of wire suitable to ensure less than
0.5V drop at 10A for the required length of the lead.
