Disable Character
Specifies the value of the RS-232 host command used to disable the reader.
ASCII characters or any hex value from 0 to 0xFF can be selected.
To set the value:
1. Determine the desired character or value. A setting of 0xFF indicates the Disable
Character is not used (not available).
2. Use the ASCII Chart on
page 345 to find the hex equivalent for the desired charac-
ter/value.
3. Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Programming
Mode.
4. Scan the bar code: SELECT DISABLE CHARACTER SETTING on
page 49.
5. Scan the appropriate two alphanumeric characters from the keypad in
Appendix D,
that represent the desired character/value determined above. The second charac-
ter will cause a two-beep indication.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit Programming Mode.
This completes the procedure. See the table below for examples of how to set this fea-
ture.
