Cordless System Operation

Note: This chapter applies only to cordless scanning systems. It does not apply to corded scanners.

How the Charge and Communications Base Works

A cordless charge and communications 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 (parame- ter menuing, visual indicator support, power-on diagnostics), and data translation required for the host system.

The cordless charge base is also a scanner’s battery charger. Refer to Charging Information, page 3-3,for additional informa- tion.

Linking the Scanner to a Base

Turn off power before connecting a base, then power up the computer once the base is fully connected. When the base is connected and powered up, put the scanner in the base to establish a link. The red LED on the base lights to indicate power, and the green LED flashes to indicate the scanner’s battery is charging.

If the scanner and base have previously been linked, you do not receive any feedback. If this is the first time that the scanner and base are linked, both devices emit a short chirp when their radios link. That indicates that the scanner is linked to the base.

To determine if your cordless system is set up correctly, scan one of the sample bar codes in the back of this manual. If the scanner provides a single good read beep and the green LED lights, the scanner has successfully linked to the base. If you receive an error tone and the red LED lights, the scanner has not linked to the base. Refer to page 12-4for troubleshooting information.

Communication Between the Cordless System

and the Host

The cordless scanner provides immediate feedback in the form of a “good read” indication (a green LED on the scanner and an audible beep) after a bar code is scanned correctly and the base has acknowledged receiving the data. This is possible since the cordless system provides two-way communication between the scanner and the base.
