Pin Arrangement
■ Connecting to the Host Device
■ RS-422 Connection
The +/ polarity designations for the SDA, SDB, RDA, and RDB signals are reversed on some devices. Always check
the signal names of the connected device and connect the polarity correctly.
■ RS-485 Connection
The internal circuits are as follows:
Pin No. Name Description
1RDA() Receive data
2 RDB(+) Receive data
3SDA() Send data
4 SDB(+) Send data
5SGSG
*Using RS-485 is possible by shorting pins 1 and 3 and
pins 2 and 4, and changing the setting to RS-485.
Note. Ground the shield at the host device to prevent malfunctions.
Note. Short pins 1 and 3 and pins 2 and 4 Do not connect
anything to the ID Controller's SG.

Note: Turn ON the terminating resistance at the nodes on both ends of the main cable.
Turn OFF the terminating resistance at all other nodes. Normal transmissions will not
be possible if the terminating resistance is ON at any node other than the end nodes.
