NAK Character
This setting specifies an ASCII character or hex value to be used as the NAK character.
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
page 394
to find the hex equivalent for the desired charac -
ter/value.
3. Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Programming
Mode.
4. Scan the bar code: SELECT NAK CHARACTER SETTING.
5. Scan the appropriate two alpha-numeric characters from the keypad in

, that represent the desired character/value determined 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 the table below for examples of how to set this fea -
ture.
