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
The ACK/NAK Characters must be different and must not contain reserved
characters (see
Appendix E, Reserved Characters
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.
1. Determine the desired character or value. Use the
on the inside back cover of
this manual to find the hex equivalent for the desired character/value.
2. Go to
and scan ENTER/EXIT PROGRAMMING MODE to enter Program-
ming Mode.
3. Scan the barcode: SELECT ACK CHARACTER SETTING.
4. 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.
5. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit.
