Introduction
SEMOD158664-5 v3
The Galvanic RS485 communication module (RS485) is used for DNP3.0 and IEC
60870-5-103 communication. The module has one RS485 communication port.
The RS485 is a balanced serial communication that can be used either in 2-wire or
4-wire connections. A 2-wire connection uses the same signal for RX and TX and
is a multidrop communication with no dedicated Master or slave. This variant
requires however a control of the output. The 4-wire connection has separated
signals for RX and TX multidrop communication with a dedicated Master and the
rest are slaves. No special control signal is needed in this case.

RS485 is a PC-MIP card, and it is factory mounted as a mezzanine card on the
Analog digital conversion module (ADM).
