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 characters. 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 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 char
ac
ter/value.
3. Go to page 38 and scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Program-
ming Mode.
4. Scan the bar code: SELECT DISABLE CHARACTER SETTING.

. Scan the appropriate two alphanumeric characters from the keypad in Appendix D, Key-
pad, that represent the desired character/value in step 1 above. The second character will 
cause a two-beep indication.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit Pr
ogramming Mode.
This completes the procedure. See Table 30 for some examples of how to set this feature.
