Basic Operation of the Cordless SystemCordless 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 communication 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.
