Commands may be strung together to create custom response sequences. An
example of a command string is listed below.
0<ESC>4<ESC>5<ESC>6,
The above example will make an image scanner in application work group zero
beep low, medium, high.
Once Host ACK is enabled, the system works as follows:
• The image scanner reads a code and sends data to the base/host system.
No audible or visual indication is emitted until you receive an escape
command. The image scanner read illumination goes out upon a successful
read.
• Image Scanner is suspended until 1) a valid escape string is received from
the host system (via the base) or 2) the image scanner “times out.”
• Once condition 1 or 2 above has been met, the image scanner is ready to
scan again, and the process repeats.
Time out is indicated by three rapid beeps at the same pitch. A time out occurs
if the source image scanner does not receive a valid escape command in 10
seconds. If a time out occurs, the operator should check the host system to
understand why a response to the image scanner was not received.
