Basic System Operation

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 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’s battery charger. Refer to "Base Charge Mode" on page 3-3for additional information.

RF (Radio Frequency) Module Operation

The cordless system uses a two-way Bluetooth radio to transmit and receive data between the image 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 a radio signal with randomly changing frequencies, makes the cordless system highly responsive to a wide variety of data collection applications and resistant to noisy RF environments. Bluetooth Class 2 power level provides a communication range of 33 feet (10m) between the image scanner and base/Bluetooth adapter, depending on the environment.

Cordless Image Scanner

The cordless image scanner enables fast and accurate bar code scanning using a non-contact area image scanner.

The image scanner is comprised of an area image engine, a decode/control assembly, and an RF communication module. The image engine performs the bar code image illumination and sensing. The decode/control assembly coordinates the central communication activities including: capturing and decoding the bar code image data, performing software activities (parameter menuing, visual indicator support, low battery indication), and data translation required for the host system. The RF communication module performs the data exchange between the image scanner and the base.
