RS-232 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
Label Transmission — the scanner expects an ACK/NAK response
from the host when a label is sent)
Host Acknowledgement — Enabled for Host Commands (the scan-
ner will respond with ACK/NAK when the host sends a command)
Label & Host — Enabled for both Label Transmission & Host
Commands
To select the option for RS-232 ACK NAK Enable:
1. Scan the SWITCH 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 fac-
ing page to ensure that the scanner reads only the bar code you
intend to scan.
3. Complete the programming sequence by scanning the SWITCH
bar code.
