Terminating resistor should be provided for a GOT and a temperature controller which will be a terminal.
For GT27 and GT25 (except for GT2505-V), set the terminating resistor to "Enable".
For GT2505-V, set the terminating resistor to "110 Ω".
➠ ■3.
Connecting terminating resistors
Connect FG grounding to the appropriate part of a cable shield line.
