1 - 10 IMAGETEAM™ 2020/5620 System Manual
The tables below list the indication and cause of the LED illumination and beeps
for the IT2020.
Note: Charging only occurs with external power applied to the IT2020 or 12 volt
Host power.
Basic Operation of the Cordless System
Cordless Base
The cordless 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
(parameter menuing, visual indicator support, power-on diagnostics), and data
translation required for the host system.
The base also is the scanner battery charger with the external 9VDC power
source applied. Once you place the scanner into base, the base green LED
responds according to the Charge Status Indicator table above.
The base can be powered by the Host (parasitic power mode). If the base is in
parasitic power mode without the 9VDC power source, the base will still function,
but will not charge the battery.
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 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
