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.
Setting to previously defined characters such as XON, XOFF, or host
commands conflicts with normal operation of these characters.
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
Programming 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 in step
1 above. The second character will cause a two-beep indication.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit.
See
for some examples of how to set this feature.
