3.6.3 RS232 Master/Slave
The RS232 master/slave connection is used to collect data from several scanners to
build either an 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 DS2400N 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. (20 mA
C.L. can also be used if the INT-22 accessory is installed).
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.
