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 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. Go to
page 28
and 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 alphanumeric characters from the keypad in
Appendix D, Keypad
, 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 Program-
ming Mode.
