ACK NAK
Options This enables/disables the ability of the reader to support the RS-232 ACK/NAK protocol. When
configured, the reader and/or host sends an “ACK” when it receives data properly, and sends
“NAK” when the data is in error.
Options are:
- Disable
- Enable for label transmission — The reader expects an ACK/NAK response from the host
when a label is sent.
- Enable for host-command acknowledge — The reader will respond with ACK/NAK when the
host sends a command.
- Enable for label transmission and host-command acknowledge
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 the inside back cover of this manual to find the hex equivalent for the
desired character/value.
3 Go to page 40 and scan ENTER/EXIT PROGRAMMING MODE to enter Programming Mode.
4 Scan the barcode: SELECT ACK 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 barcode to exit.
See Table ACK Character Setting Examples for some examples of how to set this feature.
