- There is no pin No. corresponding to TERM on the HG1F/HG2S. When inserting a
termination resistor, use a communication switch. For the setting of the switch, refer to "3
Important Points Regarding Wiring" in Chapter 1.
In MICRO/I and PLC, the name of A pole and B pole is reverse.
When you use the Terminal Block type of HG1F, make sure to configure the Hardware Flow
control to NONE because the HG1F doesn’t have control lines.
