ACK NAK Options
This enables/disables the ability of the scanner to support the RS-232 ACK/
NAK protocol. When configured, the scanner 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 scanner expects an ACK/NAK
response from the host when a label is sent
• Enable for host-command acknowledge — The scanner will respond with
ACK/NAK when the host sends a command
• Enable for label transmission and host-command acknowledge

mands conflicts with normal operation of these characters. 8-bit data is
not recognized when the option
