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.
NOTE
Setting to previously defined characters such as XON, XOFF, or
host commands conflicts with normal operation of these char-
acters. 8-bit data is not recognized when the option
Data Bits
on page 31
has been set as 7 Data Bits.
To set this feature:
1. Determine the desired character or value.
2. Use the
ASCII Chart on page 349 on the inside back cover of this manual to
find the hex equivalent for the desired character/value.
3. Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Program-
ming Mode.
4. Scan the bar code: SELECT NAK CHARACTER SETTING.
5. Scan the appropriate two alpha-numeric characters from the keypad in
Appendix D, 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 bar code to exit Programming
Mode.
This completes the procedure. See Table 7 for some examples of how to set this
feature.
