NOTE : there is only one connection per interface (RS232 or RS422 or RS485)
5. 3.1.
RS232 connection:
–
Standard PC connection
–
Sub-D 9 pins connector
–
Pin 2 : Rx
–
Pin 3 : Tx
–
Pin 5 : GND
5. 3.2.
Isolated RS485 connection
–
2 wires connection
–
« dip-switch 1 » allows connecting the terminal resistor
–
Isolation via “opto-coupler”
–
2 polarization resistors could be removed easily (if needed).
5. 3.3.
Isolated RS422 connection
–
4 wires connection
–
« dip-switch 1 and 2 » allows connecting the terminal
resistor
–
Isolation via “opto-coupler”
–
