RS-232 and RS-485 Communications Configurations
Serial communications can be configured for either RS-232 or RS-485 protocols.
On the 2-slot cradle, there are two resident RJ45 connectors, which are used to
make hardwire connections to host systems and other peripheral equipment.
For single-cradle configurations, two types of connections can be made:
dedicated mode or multidrop.
•
In multidrop mode, the user would communicate with both hand-held
units at the same time whether RS-232 or RS-485 by connecting a single
COM cable to the innermost RJ45 connector.
•
For dedicated configurations the user can communicate to each of the two
hand-helds individually by connecting two cables and by activating a small
switch located on the inside panel of the 2-slot cradle. This will separate the
signals for the two-cradle positions.
The switch is in the UP position for multidrop communications and DOWN for
dedicated configurations.
The dedicated option is not configurable for multi-cradle applications.
