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.
Setting to previously defined characters such as XON, XOFF, or
host commands conflicts with normal operation of these char-
acters. 8-bit data is not recognized when the option
Data Bits
has been set as 7 Data Bits.
To set the value:
1. Determine the desired character or value. A setting of 0xFF indicates the
Dis
able 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. Go to page 56 and scan the ENTER/EXIT PROGRAMMING MODE barcode to
enter Programming Mode.
4. Scan the barcode: SELECT DISABLE CHARACTER SETTING.
5. Scan the appropriate two alpha-numeric characters from the keypad in
Appendix D, Keypad, that represent the desired ch
aracter/value in step 1
above. The second character will cause a two-beep indication.
6. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming
Mode.
This completes the procedure. See Table 33 for some examples of how to set
this feature.
