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.
