Precautions when preparing a cable
(1) Cable length
The maximum length of the RS-422 cable differs
according to the specifications of the SHARP PLC.
For details, refer to the following manual.
SHARP PLC user's Manual
(2) GOT side connector
For the GOT side connector, refer to the following.
1.4.1 GOT connector specifications
(3) 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) GOT side
When connecting a SHARP PLC to the GOT, a
terminating resistor must be connected to the GOT.
(a) For GT16, GT15, GT12
Set the terminating resistor setting switch of the
GOT main unit to "Disable".
(b) For GT14, GT11
Set the terminating resistor selector to "330 ".
For the procedure to set the terminating resistor, refer
to the following.
1.4.3 Terminating resistors of GOT
(2) 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.
