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 va
lue. 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 35 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 c
haracter/value in step
1 above. The second character wil
l cause a two-beep indication.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit Program-
ming Mode.
This completes the procedure. See Table 36 for some examples of how to
set this feature.
