SETTING RS-422A/RS-485 TERMINATION

As it is shown in the structure map, when Controller and RS-422A/RS-485 is connected,

it should be terminated according to the Cable feature of impedance on the each end of the transmitting line to transfer the signals in long distance by controlling the reflection of the signals to the lowest.
