RS-232C connection
• Connect to the RS-232C port built in the
CPU Unit
• Connect to the RS-232C port (Ports A,
B) of the serial communication board
• Connect to the peripheral port with a
dedicated RS-232C adaptor
(CPM1-CIF01).
• Connect to the RS-232C port built in the
CPU Unit
• Connect to the peripheral port with a
dedicated RS-232C adaptor
(CPM1-CIF01).
• Connect to the RS-232C port built in the
CPU Unit or the peripheral port with a
dedicated conversion cable (CPM2C-
CN111 type, CS1W-CN118 type and
CS1W-CN114 type) (CPM2C-CN111
type is a cable that divides the Unit port
into the RS-232C port built in the CPU
Unit and the peripheral port. When
connecting to the peripheral port, a RS-
232C adaptor (CPM1-CIF01 type) is
also needed to be connected.)
• Connect to the RS-232C port built in the
CPU Unit
• Connect to the peripheral port with a
conversion cable (CS1W-CN118 type)
Connect to the RS-232C port (Port 1) of
the serial communication board

RS-422A connection
• Connect to the RS-422A port (port A) of
the serial communication board
• Connect to the peripheral port with a
dedicated RS-422A adaptor
(CPM1-CIF11 type).
• Connect to the peripheral port with a
dedicated RS-422A adaptor
(CPM1-CIF11 type).
• Connect to the peripheral port with a
dedicated conversion cable (CPM2C-
CN111 type or CS1W-CN114 type) and
a RS-422A adaptor (CPM1-CIF11 type)
(CPM2C-CN111 type is a cable that
divides the Unit port into the RS-232C
port built in the CPU Unit and the
peripheral port).
• Connect to the RS-422A port (Port 2) of
the serial communication board
