enable connecting to a personal computer with a CS1W-CN226/CN626
Connecting Cable.
Note a)The C200H-PRO27-E Programming Console can be connected di-
rectly to the CPM2C's CPU Unit using a special connecting cable
(CS1W-CN224/624).
b)Use the CS1W-CN114 when using the port as a peripheral port.
c)Use the CS1W-CN118 when using the port as a RS-232C port.
2. Cable Switch (SW1, CPM2C-CIF01-V1 Only)
Turn ON SW1 to use a CS1W-CN226/CN626 Connecting Cable to connect
to a personal computer. Turn OFF SW1 to use any other cable.
3. RS-232C Port
Used to connect to the RS-232C interface of a personal computer or Pro-
grammable Terminal (operator interface).
