3.2.3 RS422/485 2-wire (DM Link 1:N Communication: N=2)
In the following diagram, only describe the terminal name.
Refer to Chapter 4 "3.2.2 2-wire" on page 569 for the correspondence between the terminal name and the pin number
If more than one MICRO/I or Touch are connected to an external device, select “RS422/485 2-wire” as “Serial Interface”.

- There is no pin number corresponding to TERM on the HG1F/HG2S. When inserting a termination resistor, use a commu-
nication switch. For the setting of the switch, refer to Chapter 1 "3 Important Points Regarding Wiring" on page 19.
- If more than one MICRO/I or Touch are connected to an external device, select “RS422/485 2-wire” as “Serial Interface”.
- Touch has no pin number corresponding to TERM. When a termination resistor is necessary, insert one with suitable resis-
tance value between pin 8 (RDA) and pin 9 (RDB).
