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 chara
cters 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.
