- 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.
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.
