2.5.3 RS232 

Master/Slave

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 DS2100 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 main serial interface. The possible
main interface types for the master scanner are RS232 or RS485.

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.
