Typical layouts
The following typical layouts refer to system hardware configurations. Dotted lines in
the figures refer to optional connectivity within the particular layout.
5.5.1
Point-to-point
In this layout data is transmitted to the Host on the RS 232 auxiliary serial interface.
When on-line operating mode is used, the scanner is activated by an external trigger
(photoelectric sensor) when the object enters its reading zone.

Point-to-point layout
5.5.2
RS 485 master/slave
The RS 485 master/slave connection is used to collect data from several scanners to
build a multi-point or a multi-sided reading system; there can be one master and up
to 5 slaves connected together.
The Slave scanners are connected together using the RS 485 half-duplex main serial
interface. Every slave scanner must have a multidrop address in the range 0 to 4.
These layouts also require the correct setup of the software
configuration parameters. Complete software configuration procedures
can be found in the
Guide To Rapid Configuration
in the VisoSetup
Help On Line.
The local echo communication mode must be enabled (default). See
the VisoSetup Help On Line.
