Precautions when preparing a cable
(1) Cable length
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-

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, GT10
