Pin 1 TR- / D1 Out RS485 TX/RX-
Pin 2 TR+ / D0 Out RS485 TX/RX+
Pin 5 GND Ground for Wiegand / RS485 / Dataclock
For a half-duplex RS485 connection, only Tx/Rx+ , Tx/Rx- and ground reference
signals are necessary.
Depending on RS485 network , an impedance adaptation may be required.
A 120 Ohms resistor termination may be added to the terminal , by strapping pin 1
and pin 2 of the auxiliary connector.
