IMAGETEAM™ 2020/4620 System Manual 1 - 9
Communication Between the Cordless System and the
Host
The cordless imager provides immediate feedback in the form of a “good read”
indication (a green LED on the imager 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 imager and the base.
When data is scanned, the data is sent to the host system via the base unit.
Confirmation from the host system or the base indicates that the data sent was
received by the host. The cordless imager recognizes data acknowledgement
(ACK) from the base unit. If it cannot be determined that the data has been
properly sent to the base, the imager issues an error indication. You must then
check to see if the scanned data was received by the host system.
