Basic Operation of the Cordless System

Cordless Base

The cordless base provides the link between the cordless 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 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 scanner battery charger with the external 9VDC power source applied. Once you place the 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 function, but will not charge the battery.

RF (Radio Frequency) Module Operation

The cordless system uses a state-of-the-art two-way Bluetooth radio to transmit and receive data between the scanner and the base. Designed for point-to-point and multipoint-to-single point applications, the radio operates using a license free ISM band, which sends relatively small data packets at a fast data rate over
