6.5 MULTIPLEXER
(21x-x0x and 21x-x1x models)
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 103 - 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.
