6.4 RS232 MASTER/SLAVE
NOTE
This interface is provided for backward compatibility. We recommend using
the more efficient ID-NET™ network for Master/Slave or Multiplexer layouts.
The RS232 master/slave connection is used to collect data from several readers to build either
a multi-point or a multi-sided reading system; there can be one master and up to 9 slaves
connected together.
The Slave readers use RS232 only on the main and auxiliary serial interfaces. Each slave
reader transmits the messages received by the auxiliary interface onto the main interface. All
messages will be passed through this chain to the Master.
The Master reader is connected to the Host on the RS232/RS485 main serial interface.
There is a single reading phase and a single message from the master reader to the Host
computer.
In this layout the Master operating mode can be set only to Phase Mode.
The Phase ON/OFF signals must be brought only to the Master. It is not necessary to
bring them to the Slave readers.
The main and auxiliary ports are connected as shown in the figure below.
