Communication Between The Cordless System And The Host; Rf (Radio Frequency) Module Operation - Honeywell Voyager 1200g User Manual

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 12-5 for 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.
When data is scanned, the data is sent to the host system via the base. The
cordless scanner recognizes data acknowledgement (ACK) from the base. If it
cannot be determined that the data has been properly sent to the base, the
scanner issues an error indication. You must then check to see if the scanned
data was received by the host system.

RF (Radio Frequency) Module Operation

The cordless system uses a two-way Bluetooth® radio to transmit and receive
data between the scanner and the base. Designed for point-to-point and multi-
point-to-single point applications, the radio operates using a license free ISM
band. This band sends relatively small data packets at a fast data rate over a
radio signal with randomly changing frequencies. This makes the cordless sys-
tem highly responsive to a wide variety of data collection applications and resis-
