The remote connector is a 9-pin subminiature male D connector (J6) located on the rear
panel of the modem. Screw locks are provided for mechanical security of the mating
connector.
The remote connector interfaces the M & C functions to a remote location. The remote
location can be an M&C computer located away from the modem, but attached via cable to
the remote connector. This DCE interface is user selectable for either RS-232 or RS-485.
