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
The distance between the GOT and the PLC of
connection diagram 1), 2) and 3) must be 1200 m or
less.
The length of the RS-422 connection diagram 4) or RS-
422 connection diagram 5) must be 30m or less.
For the GOT side connector, refer to the following.
1.4.1 GOT connector specifications
Connecting terminating resistors
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.
