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. 8-bit data is not recognized when the option
has been set as 7 Data Bits.
