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.

• Disable
• Enable for label transmission — The reader expects an ACK/NAK response from the host
