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 the inside back cover of this manual to find the hex equivalent
for the desired character/value.
3. Go to page 19 and scan the ENTER/EXIT PROGRAMMING MODE barcode to enter
Programming Mode.
4. Scan the barcode: SELECT NAK CHARACTER SETTING.
5. Scan the appropriate two alphanumeric characte
rs from the keypad in Appendix D,
Keypad, that represent the desired character/value in step 1 above. The second charac-
ter will cause a two-beep indication.
6. Scan the ENTER/EXIT PROGRAMMING MODE barcod
e to exit Programming
Mode.
This completes the procedure. See Table 27 for some examples of how to set this feature.
Table 27. NAK Character Setting Examples
ACK NAK Timeout Value
This option specifies the amount of time the scanner waits for an ACK character from the
host following label transmission. The selectable timeout range is 200 milliseconds to
15,000ms (15 seconds) in 200ms increments. A selection of 0 disables the timeout.
To set this value:
1. Determine the desired setting in mi
lliseconds.
Setting to previously defined characters such as XON, XOFF, or host
commands conflicts with normal operation of this character.
