NOTE
The auxiliary serial interface of the slave scanners can be used in
Local Echo communication mode to control any single scanner
(visualize collected data) or to configure it using the WinHost utility or
Host Mode Programming procedure.
The termination resistors of the RS485 bus must not be installed.
2.6.5 Multiplexer
Each scanner is connected to Multiplexer (for example MX4000) with the RS485 half-
duplex main interface.

The auxiliary serial interface of the slave scanners can be used in Local Echo
communication mode to control any single scanner (visualize collected data) or to
configure it using the WinHost utility or Host Mode Programming procedure.
When On-Line Operating mode is used, the scanner is activated by an External
Trigger (photoelectric sensor) when the object enters its reading zone.
