TYPICAL LAYOUTS

105

6.5 MULTIPLEXER

NOTE

This interface is provided for backward compatibility. We recommend using

the more efficient ID-NET™ network for Master/Slave or Multiplexer layouts.

Each reader is connected to a Multiplexer (for example MX4000) with the RS485 half-duplex

main interface through a CBX connection box.

Before proceeding with the connection it is necessary to select the MUX32 communication

protocol and the multidrop address for each reader.

Figure 114 - Multiplexer Layout

The auxiliary serial interface of the slave readers can be used in Local Echo communication

mode to control any single reader (visualize collected data) or to configure it using the

VisiSet™ utility.

Each reader has its own reading phase independent from the others. When One Shot or

Phase Mode operating mode is used, the reader can be activated by an External Trigger (for

example a pulse from a photoelectric sensor) when the object enters its reading zone.
