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 com-
mands conflicts with normal operation of these characters. 8-bit data is not
recognized when the option
has been set as 7 Data Bits.

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 Program-
ming Mode.
4. Scan the barcode: SELECT ACK CHARACTER SETTING.
5. Scan the appropriate two alpha-numeric characters from the keypad in
, that represent the desired character/value in step 1 above. The second character will
cause a two-beep indication.
