Enable Character
Specifies the value of the RS-232 host command used to enable 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 this feature:
Determine the desired character or value. A setting of 0xFF indicates the Enable Character is
not used (not available).
1. Determine the desired character or value.
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 38 and scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Program-
ming Mode.
4. Scan the bar code: SELECT ENABLE CHARACTER SETTING.
5. Scan the appropriate two alphanumeric characters from the keypad in
Appendix D, Key-
pad , that represent the desired character/value in step 2 above. The second character will
cause a two-beep indication.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit Programming Mode.
This completes the procedure. See Table 31 for some examples of how to set this feature.
