*1 A terminating resistor is required.
Set the terminating resistor selector switch in the main unit to "Disable", and connect a terminating resistor (110 Ω).
*2 For terminating resistors in PLCs manufactured by MITSUBISHI INDIA, refer to the manual of PLCs manufactured by
MITSUBISHI INDIA.
*3 Use a twisted pair cable for the SDA1/SDB1.
