RS-232 Features
Product Reference Guide 143
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.
RS-232 ACK NAK = DISABLE
RS-232 ACK/NAK = LABEL TRANSMISSION
