Terminal

- There is no pin number corresponding to TERM on the HG2G-S/-5S/-5F, HG3G/4G. When inserting a termination resis-

tor, use a communication switch. For the setting of the switch, refer to Chapter 1 "3 Important Points Regarding Wiring"
on page 19

- HG2G-5F, HG3G/4G Series uses only RDA and RDB when using RS422/485 2-wire, you don’t need to connect SDA or

SDB.
If connecting COM1 on the HG2G-5F, HG3G/4G to the external device, do not insert terminating resistor to the external
device. If terminating resistor can not be removed, use COM2 on the HG2G-5F, HG3G/4G instead of COM1.
