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
whe
n 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.
NOTE
Setting to previously defined characters such as XON, XOFF, or host commands
conflicts with normal operation of these characters. 8-bit data is not recog-
nized when the option
Stop Bits
has been set as 7 Data Bits.
