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 char-
acters. 8-bit data is not rec
ognized when the option
Data Bits
has been set as 7 Data Bits.
To set this feature:
1. Determine the desired c
haracter or value.
2. Use the ASCII Chart on the inside back cover of th
is manual to find the
hex equivalent for the desired character/value.
3. Go to page 32 and scan the ENTER/EXIT PR
OGRAMMING 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
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 cod
e to exit Program-
ming Mode.
This completes the procedure. See Table 33 for some examples of how to
set this feature.
