Basic System Operation
Cordless Base
The cordless base provides the link between the cordless imager 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 imager 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 imager’s battery charger. Refer to
"Base Charge Mode"
on
page 3-3 for additional information.
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 imager 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 range of 33
feet (10m) depending on the environment.
Cordless Imager
The cordless imager enables fast and accurate bar code scanning using a non-
contact area imager.
The imager is comprised of an area imager, a decode/control assembly, and an
RF communication module. The scan 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 imager
and the base.
