A, B, C, J: RS-485
These four pins form a standard RS-485 port, with RX+, RX-, TX+, TX-. Use Pin G or H as the ground
reference for this port.
TX+ and TX- are the differential pair which carries a signal from the host computer to the unit. RX+ and
RX- are the differential pair which carries a signal from the unit to the host computer. Ensure these are
connected to the host computer RS-485 port accordingly.
 A
TX- (RS-485) Host computer TX- signal (signal into unit)
 B
TX+ (RS-485) Host computer TX+ signal (signal into unit)
 C RX+ (RS-485) Host computer RX+ signal (signal out of unit)
 J RX- (RS-485) Host computer RX- signal (signal out of unit)

E, F: RS-232
Pins E and F form a standard RS-232 port, with RX and TX. Use Pin G or H as the ground reference for
this port. Ensure these are connected to the host computer RS-232 port accordingly.
 E
RX (RS-232) Host computer RX signals (signal out of unit)
 F TX (RS-232) Host computer TX signals (signal into unit)
