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
Data Bits
has been set as 7 Data Bits.
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

ming 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.
