RS485 two wirings terminal, A
(DATA
+), B (DATA), when connected with RS485, A (+) to
A (+), B (-) to B (-).
RS422 interface also connected to RS232 nine needles binding post. The device have RS232
and RS485 interface, but can only use one in a time, autoadaptation, connect as RS485 is RS485
function, connect as RS422 wiring is RS422 function.
