9. CONNECTION TO RKC TEMPERATURE CONTROLLER
9.3 Connection Diagram
(7) RS-485 connection diagram 7)
*1 Set the terminating resistor setting switch of the GOT main unit to "100 OHM".
■ Connecting terminating resistors
*2 When combining the module, because the communication line is connected between the modules with each other, wire only the
communication terminal on the both end of the combination module.
*3 Terminating resistor should be provided for a temperature controller which will be a terminal. When using X-TIO, turn ON the
terminating resistor selector in the terminal base. When combining the module, provide the terminating resistor to the end of the
combination module (the one that is far from the converter).
*4 For the terminal number for connecting to FB series or RB series, refer to the table below.
