4.1RS-232C

(This section applies to the RS-232C or RS-485.)

All EPM 5300P and 5200P instruments can be equipped with RS-232C or RS-485 communication.

RS-232C communication links a single instrument with a computer or device such as an RTU or PLC. Its capability is up to 100 feet. A standard 9-pin female serial port connector mounts on the instrument for direct connection to a computer with a 9-pin cable.
