socomec Green Power 2.0 - CONNECTIONS AND WIRING; RS232 Connection Details; Isolated RS485 Connection; Isolated RS422 Connection

5. 4. connEctions and wiring
NOTE : there is only one connection per interface (RS232 or RS422 or RS485)
5. 4.1. RS232 connection:
– Standard PC connection
– Sub-D 9 pins connector
– Pin 2 : Rx
– Pin 3 : Tx
– Pin 5 : GND
5. 4.2. Isolated RS485 connection
– 2 wires connection
– « dip-switch 1 » allows connecting the terminal resistor
– Insulation via “opto-coupler”
– 2 polarization resistors could be removed easily (if needed).
5. 4.3. Isolated RS422 connection
– 4 wires connection
– « dip-switch 1 and 2 » allows connecting the terminal
resistor
– Insulation via “opto-coupler”
– 4 polarization resistors could be removed easily (if needed).

Before making any connection, please check the cabling. A wrong connection or cabling can damage
the serial link interface.
