- In case of HG2F/3F/4F a connection cable is available (part number: HG9Z-3C165).
- In case of HG1F a connection cable is available (part number: HG9Z-XC255).
- 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 connect to the CPU port of MELSEC-A series and MELSEC-FX series of
Mitsubishi Electric, use D-sub 9Pin connector, NOT the Terminal Block type.
