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
