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
Appendix G, 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.
Table 12 - NAK Character Setting Examples
NOTE: 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 on
page 53 has been set as 7
Data Bits.
