*1 Terminating resistor should be provided for a temperature controller which will be a terminal.
The value of terminating resistor varies between GT15, GT14, GT12 and GT11.Set the value as follows.
For the GT15, GT12: 100
For the GT14, GT11: 220
*2 Set the terminating resistor of GOT side which will be a terminal.
