RS485 Full-Duplex

The RS485 full-duplex interface is used for non-polled communication protocols in point-to-point connections over longer distances than those acceptable for RS232 communications or in electrically noisy environments.

The following pins of the 25-pin connector are used for RS485 full-duplex communications:

Pin	Name	Function

2	TX485+	RS485 transmitted data +
4	TX485-	RS485 transmitted data -
3	RX485+	RS485 received data +
5	RX485-	RS485 received data -
7	SGND Main	signal ground main interface
	DS4300	USER INTERFACE
