The RS-485 Port
Over short distances the wiring diagram shown below is compatible with an RS-232 port. There is no
standard pin configuration for RS-485 on a DB9 connector. The wiring diagram shown will connect
directly to a RS-232 configured DB9 without the need for a RS-232/RS-485 converter.

A demarcation point is recommended to allow the RTMS to be disconnected from the transmission line
without disruption of communications with other sensors on the line. See Connecting RTMS to
