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

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.
