.
SC100:
Connect RS232 communications cable to the front connector.
Ensure the cable is secured so that no force is applied to the RS232 connector as
this may damage the connector.
SC200:
Connect Ethernet and/or RS232 communications cables to the rear
connectors:
1
Undo the retaining screw and partly withdraw the SC200.
2
Route the communications cable(s) from the SC200 position, through the APS to
the I/O panel cable access hole at the rear.
3
Connect the communications cable(s) to the connector(s) on the rear of the
SC200.
RS232 connection access is restricted. If necessary, use a DB9 ribbon cable
extension (Farnell part number 869-6411 or similar).
