For GT27 and GT25 (except for GT2505-V), terminating resistor should be provided for an Interface converter and a control
equipment which will be terminals.
Connect FG grounding to the single-sided end of a cable shield line.
Set the terminating resistor of GOT as follows.
For GT27 and GT25 (except for GT2505-V), set the terminating resistor to "Disable".
For GT2505-V and GT21, set the terminating resistor to "110 Ω".
