RER 133
Technical Description
General
The RER 133 Bus Connection Module acts as an interfacing unit between an
RE_54_ host device and a SPA, Modbus or DNP 3.0 system. The RER 133 module
converts RS-232 signals to RS-485 signals. RS-485 can be connected by using 2- or
4-wire mode.
The RER 133 module is connected by a cable to the RS-232 D-type connector
marked X3.2 on the rear panel of the RE_ 54_ host device. RER 133 is not a stand
alone device. An RE_ 54_ host device is always required to power the module. No
external power supply is supported.
RER 133 supports communication speeds from 300 to 19200 bits/s. Collision
detection and collision avoidance is supported for communication speeds 4800,
9600 and 19200 bits/s.
A RER 133 delivery includes the RER 133 Bus Connection Module, a connection
cable (1MRS120542) and this manual.
