Hand Held Products 2020/5620 system manual Host ACK Enable, 0ESC4ESC5ESC6

The commands to which the scanner responds are listed on page 2-12. The <ESC> is a 1B in hex. A typical command string is y <ESC> x, where “y” is the application work group number, “<ESC> x” is the escape command, and the comma is the terminator.

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 a scanner in application work group zero beep low, medium, high.

Once Host ACK is enabled, the system works as follows:

•The 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 scanner read illumination goes out upon a successful read.

•Scanner is suspended until 1) a valid escape string is received from the host system (via the base) 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.

Time out is indicated by three rapid beeps at the same pitch. A time out occurs if the source 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 scanner was not received.
