NAK Character
This setting specifies an ASCII character or hex value to be used as the NAK charac-
ter. ASCII characters or any hex value from 0 to 0xFF can be selected.
To set this feature:
1. Determine the desired character or value.
2. Use the
ASCII Chart
on the inside back cover of this manual to find the hex equiv-
alent for the desired character/value.
3. Scan the ENTER/EXIT PROGRAMMING MODE barcode to enter Program-
ming Mode.
4. Scan the barcode: SELECT NAK CHARACTER SETTING.
5. Scan the appropriate two alpha-numeric characters from the keypad in
Appendix
E, 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 barcode to exit Program-
ming Mode.
This completes the procedure. See
Table 9
for some examples of how to set this fea-
ture.
