3.6.3 RS232 Master/Slave
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
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 main serial interface. The possible main
interface types for the Master reader are RS232 or RS485.
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.
