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.
Termination : Using numbers 1 and 2 PIN, turn to <
