RS-232 ACK NAK Features
ACK NAK Enable
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. Selections
for this option are:
•Disable ACK NAK
• Enable for Label Transmission — the scanner expects an ACK/NAK
r
esponse from the host when a label is sent)
• Enable for Host Acknowledgement — Enabled for Host Commands (the
scanner will respond
with ACK/NAK when the host sends a command)
• Enable for Label & Host — Enabled for both Label Trans
mission & Host
Command acknowledgement.
To select the option for RS-232 ACK NAK Enable:
1. Scan the Enter/Exit Progr
amming Mode bar code.
2. Scan the desired option from bar codes below and
on the following page.
You’ll need to cover any unused bar codes on this and the facing page to
ensure that the scanner reads only the bar code you intend to scan.
3. Complete the programming sequence by
scanning the Enter/Exit Pro-
gramming Mode bar code.
