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 scanner will respond with ACK/NAK when the host sends a com- mand)

Label & Host — Enabled for both Label Transmission & Host CommandsTo select the option for RS-232 ACK NAK Enable:
