Basic Operation of the Cordless System

Cordless Base
The cordless base provides the link between the cordless image scanner and
the host system. The base contains an interface assembly and an RF commu-
nication module. The RF communication module performs the data exchange
between the cordless image scanner and the interface assembly. The control
assembly coordinates the central interface activities including: transmitting/
receiving commands and data to/from the host system, performing software
activities (parameter menuing, visual indicator support, power-on diagnostics),
and data translation required for the host system.
The base also is the image scanner battery charger with the external 9VDC
power source applied. Once you place the image scanner into base, the base
green LED responds according to the Charge Status Indicator table above.
The base can be powered by the Host (parasitic power mode). If the base is in
parasitic power mode without the 9VDC power source, the base will still func-
tion, but will not charge the battery.
