ACK NAK Options
This enables/disables the ability of the scanner to support the RS-232 ACK/
NAK protocol. When configured, the scanner 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 scanner expects an ACK/NAK
response from the host when a label is sent
• Enable for host-command acknowledge — The scanner 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
on the inside back cover of this manual to
find the hex equivalent for the desired character/value.
3. Go to
and scan ENTER/EXIT PROGRAMMING MODE to enter Pro-
gramming Mode.
4. Scan the bar code: SELECT ACK CHARACTER SETTING.
5. Scan the appropriate two alphanumeric characters from the keypad in
, that represent the desired character/value determined
above. The second character 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.
