Terminating Resistor Settings - Mitsubishi Electric LE7-40GU Instruction Manual

Terminating resistor settings

Be sure to install terminating resistors at both ends of the line.
LE7-40GU, the built-in RS-485 port of the CPU module, FX5-485-BD, and FX5-485ADP, have built-in terminating resistors.
Set the terminating resistance with the terminating resistor changeover switch.
