ACK Character
This setting specifies an ASCII character or hex value to be used as the ACK character.
ASCII characters or any hex value from 0 to 0xFF can be selected.
1. Determine the desired character or value.
2. Use the ASCII Chart on
page 288 to find the hex equivalent for the desired charac-
ter/value.
3. Scan ENTER/EXIT PROGRAMMING MODE to enter Programming Mode.
4. Scan the bar code: SELECT ACK CHARACTER SETTING.
5. Scan the appropriate two alphanumeric characters from the keypad in
Appendix D,
that represent the desired character/value determined above. The second charac-
ter will cause a two-beep indication.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit.
See the table below for examples of how to set this feature.
