3 Precautions when preparing a cable
The length of the RS-422 cable must be 1km or less.
4 Connecting terminating resistors
When connecting an TOSHIBA PLC to a GOT, a terminating resistor must be set to the TOSHIBA PLC.
No terminating resistor needs to be connected on the GOT side as one is already built into the GOT.
For the setting of the terminating resistor, refer to the following manual.
User's Manual for the TOSHIBA PLC
