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 scanners 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 scanners use RS232 only on the main and auxiliary serial interfaces. Each slave
DS4800 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 scanner 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 scanner to the Host computer.
Either On-Line or Serial On-Line Operating modes can be used in this layout.
When On-Line Operating mode is used, the external trigger signal is unique to the system, however it is not necessary to bring the external trigger signal to the Slave scanners.
The main and auxiliary ports are connected as shown in the figure below.
