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 the Disable
Character is not used (not available).
2. Use the ASCII Chart on the inside back cover of this manual to find the hex equivalent
for the desired character/value.
3. Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Programming
Mode.
4. Scan the bar code: SELECT DISABLE CHARACTER SETTING.
5. Scan the appropriate two alpha-numeric characters from the keypad in Appendix E,

will cause a two-beep indication.

Mode.
This completes the procedure. See Table 12 for some examples of how to set this feature.
