Connection diagram
(1) RS-485 connection diagram 1)
*1 Pin No. of temperature controller differs depending on the model. Refer to the following table.
*2 Terminating resistor should be provided for a temperature controller which will be a terminal.
*3 Turn on the terminating switch on the RS232C/RS485 converter at the end.
*4 Connect FG grounding to the appropriate part of a cable shield line.
(2) RS-485 connection diagram 2)
*1 Pin No. of temperature controller differs depending on the model.Refer to the following table.
*2 Terminating resistor should be provided for a temperature controller which will be a terminal.
*3 Set the terminating resistor of GOT side which will be a terminal.
