Communication Between the Cordless System
and the Host
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.

the scanner and the base.
When data is scanned, the data is sent to the host system via the base unit.
The cordless scanner recognizes data acknowledgement (ACK) from the base
unit. 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, which sends relatively small data packets at a fast data rate over a radio
point-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 communica-
tion range of 33 feet (10m) between the scanner and base/Bluetooth adapter,
depending on the environment.

System Conditions
The components of the cordless system interact in specific ways as you associ-
ate a scanner to a base, as you move a scanner out of range, bring a scanner
back in range, or swap scanners between two cordless systems. The following
ate a scanner to a base, as you move a scanner out of range, bring a scanner
back in range, or swap scanners between two cordless systems. The following
information explains the cordless system operating conditions.
3) Base sends data to host
1) Good Read
2) ACK from base
