
Precautions when preparing a cable
(1) Cable length
The total distance (between GOT and controllers) of
RS-422 cable must be 13m or less.
(2) Connector conversion box side connector
For the connector conversion box side connector, refer
to the following.
6.6 Connector Conversion Box
(3) External cable side connector
For the connector specifications of the external cable
side, refer to the following.
8.2 External Cable, Relay Cable
(4) SHARP PLC side connector
Use the connector compatible with the SHARP PLC
side module.
For details, refer to the SHARP PLC user's manual.

Connecting terminating resistors
(1) SHARP PLC side
Connect the terminating resistor on the SHARP PLC
side when connecting a GOT to a SHARP PLC.
The PLC CPUs and the modules on the PLC CPU side
requiring a terminating resistor are shown below.
(a) JW-22CU
Turn "ON" the terminating resistor setting switch
(SW1) on the back of JW-22CU to validate the
terminating resistor.
(b) JW-70CUH and JW-100CUH
Connect the pin 6 (terminating resistor) of the
communication port connection connector with the
pin 13 (RXD) only at the terminal station to validate
the terminating resistor.
(c) JW-21CM, JW-10CM and ZW-10CM
Turn "ON" the terminator switch (SW7) on the front
panel only at the terminal station to validate the
terminating resistor.
