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
