14.4 Wiring
When construct a RS-422/485 network using K200S B type CPU module, please connect a
terminal resistor at the both ends of network. It prevent the signal from distortion by reflected
wave. The resistance value of terminal resistor should be equal to the characteristic impedance
of network cable (usually 120Ω, 1/2W resistor)
