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.
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
has been set as 7 Data Bits.
To set this feature:
1. Determine the desired character or value.
2. Use the ASCII Chart
acter/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 NAK CHARACTER SETTING.
5. Scan the appropriate two alphanumeric characters from the keypad in
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 Programming Mode.
This completes the procedure. See
