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.
