The above example will make a scanner that is in application work group zero beep
low, then medium, then high.
Example: A good read beep is required for any item on file, but a razz or error tone is required
if the item is not on file. In this case,
[ESC]7, is sent to the host for an on-file product
[ESC]8,[ESC]8, is sent to the host for a not-on-file product
When a bar code is scanned, the scanner enters a timeout period until either the
host ACK sequence is received, or the timeout expires (in 10 seconds, by default).
Once Host ACK is enabled, the system works as follows when a bar code is
scanned:
•
•
•
A timeout occurs if the scanner does not receive a valid escape command within
the timeout period. A timeout is indicated by an error tone. If a timeout occurs, the
operator should check the host system to understand why a response to the scan-
ner was not received.
Host ACK On/Off
Voyager 1470/1472 User Guide
The scanner reads the code and sends data to the base or Access Point to
transmit to the host system. No audible or visual indication is emitted until the
scanner receives an escape command. The scanner read illumination goes out
when there's a successful read.
Scanner operation is suspended until 1) a valid escape string is received from
the host system or 2) the scanner times out.
Once condition 1 or 2 above has been met, the scanner is ready to scan again,
and the process repeats.
