PS4-201-MM1 to Red Lion Controls

Knowledge of Unit Operation Is Assumed
In all cases, both familiarity with the control functions and knowledge of system operation are assumed.

Communications with the Klockner Moeller PS4-201 is via an RS-232 point-to-point link. The default serial communications format is RS-232, baud rate of 9600, 8 data bits, No parity, and 2 stop bits. RS-485 multi-drop cannot be used due to a baud rate incompatibility. The Moeller K-Suconet RS-485 port communicates at either 187.5K baud or 375K baud, whereas the current line of Red Lion HMI's cannot communicate at either of those baud rates.

The connection details are described in the table below.

Name Connector Pin Out
1 CTS 1, 6 --
2 Rx 2 5
3 COMM 3 3
4 COMM -- --
5 Tx 5 2
6 RTS 1, 6 --

The above table denotes the pin names of the RS232 port.
When connecting, the pin name at the RS232 port is connected
to the opposite of that pin name at the destination device.
