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 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 cord-
less system highly responsive to a wide variety of data collection applications
and resistant to noisy RF environments. Bluetooth Class 2 power level provides
range of 33 feet (10m) depending on the environment.
Cordless Image Scanner
The cordless image scanner enables fast and accurate barcode scanning using
a non-contact linear image scanner.
The image scanner is comprised of a linear image scanner, a decode/control
assembly, and an RF communication module. The scan engine performs the
barcode image illumination and sensing. The decode/control assembly coordi-
nates the central communication activities including: capturing and decoding
the barcode 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.
System Conditions
The components of the cordless system interact in specific ways as you associ-
ate an image scanner to a base, as you move an image scanner out of range,
bring an image scanner back in range, or swap image scanners between two
cordless systems. The following information explains the cordless system oper-
ating conditions.
Linking Process
Once an image scanner is placed into the base, the image scanner’s battery
charge status is checked, and software automatically detects the image scan-
ner and links it to the base depending on the selected link mode.
Image Scanner Is Out of Range
The cordless image scanner is in communication with its base, even when it is
not transmitting barcode data. Whenever the image scanner can’t communi-
cate with the base for a few seconds, it is out of range. If the image scanner is
out of range and you scan a barcode, the image scanner issues a triple beep
indicating no communication with the base. In addition, your image scanner
and base can sound an alarm if programmed to emit an alarm. See Out-of-
Range Alarm on page 1-12.
Image Scanner Is Moved Back Into Range
The image scanner re-links if the image scanner or the base have been reset or
out of range. If the image scanner re-links, you will hear a single chirp when the
re-linking process (uploading of the parameter table) is complete.
