RS485 Half-Duplex Interface

The RS485 half-duplex (3 wires + shield) interface is used for polled communication protocols.

It can be used in a master/slave layout or for Multidrop connections with a Datalogic Multiplexer, (see par. 2.6.4 and 2.6.5).

The connector pinout follows:

Pin	Name				Function
2	RTX485+				RS485 transmitted/received data +
4	RTX485-				RS485 transmitted/received data -
7	SGND				Signal Ground
	DS2400					MULTIPLEXER
			2		RTX485 +			RTX485 +


			4		RTX485 -			RTX485 -


			7		SGND			RS485REF

Figure 2.15 - RS485 half-duplex connections

This interface is forced by software when the protocol selected is MUX32 protocol.

In a Multiplexer layout or for slaves, the Multidrop address must also be set via serial channel by the WinHost utility or by ESC sequences.
