The polarity A and B in signal names may be reversed
depending on the microcomputer to be used.
Prepare a cable according to the microcomputer to be
used.
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.

Connecting terminating resistors
(1) GOT side
When connecting a microcomputer to the GOT, a
terminating resistor must be connected to the GOT.
Set the terminating resistor setting switch of the GOT
main unit to "Disable".
For the procedure to set the terminating resistor, refer
to the following.
