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 character. ASCII
characters or any hex value from 0 to 0xFF can be selected.

Setting to previously defined characters such as XON, XOFF, or host com-
mands conflicts with normal operation of these characters. 8-bit data is not
recognized when the option

Data Bits

has been set as 7 Data Bits.
