3.4.2 SLM-5650C-ODU Remote Connector (DB9)
This is a male Type ‘D’ 9-pin subminiature (DB9) connector that serves multi-
purpose roles. It provides RS-232 communications for a remote terminal, it
provides a means to monitor the real time I and Q samples from the demodulator
(constellation monitor), and it provides a receive signal strength indicator that can
be used to aid in peaking an antenna.
The DB9 connector is not a standard RS-232 serial port pinout.
