Appendix A
Programming the Scanner
Two different methods can be used to program parameters to configure the scanner:
a. Programming via Computer Commands
b. Programming via special Bar Codes from a menu page
Most parameters can be programmed using either of these two methods. However, there are certain
parameters that are only programmable via the bar code menu.
a. Programming via Computer Commands
Parameters can be programmed by sending software commands or keyboard strokes from the host
computer to the scanner in the following format:
<ESC> Computer Command <CR>
Note:
Only upper case letters are recognized, e.g., “AB” not” ab”
Each command normally consists of two characters
Downloading of software commands cannot be “grouped” together. Each command
must be preceded by <ESC> or <STX> and followed by a <CR> or <ETX>
Parameters programmed by downloaded commands can be stored permanently by transmitting a
“<ESC> Z2 <CR>” command. It is not necessary to send a “Z2” command after each parameter that is
changed. One Z2 command will save all changes.
Appendix B lists all of the Computer Commands. In Appendix C, Bar Code Programming Menus, the left-
hand column in all menus contains the Computer Command associated with that bar code.
b. Programming via Bar Codes
Use the following steps to program parameters via the bar code menus:
1.
Scan the “Start/End” bar code. This instructs the scanner to enter the Programming Mode.
While in this mode the scanner will beep intermittently.
2.
Scan the bar code(s) associated with the desired parameter(s). The scanner will beep when the
bar code is read. Note: because of the close proximity of bar codes on the page, it is important
to aim carefully to ensure that only the desired bar code is scanned.
3.
Scan the “Start/End” bar code. This instructs the scanner to exit the Programming Mode.
All the parameters that were scanned are retained in non-volatile memory and are stored permanently
(even if the scanners is powered down) or until they are changed again.
