Resolution / Answer
This article introduces the purpose and configuration method of "software handshake". Usually refer to this article when you need to change the default behavior of the device, adapt to the business system, or find the corresponding configuration barcode.
This parameter provides control over the data transfer process in addition to that provided by the hardware handshake. Hardware handshaking is always enabled and cannot be disabled by the user.
Disable ACK/NAK handshake
When this option is selected, the scan engine neither generates nor requests an ACK/NAK handshake.
Scan the following barcode to disable ACK/NAK.
Enable ACK/NAK handshake
When this option is selected, the scan engine expects an ACK or NAK response from the host after sending data. The scan engine can also send ACK or NAK messages to the host.
The scan engine waits at most for a programmable host serial response timeout to receive an ACK or NAK. If the scan engine does not receive a response within this time, it will have up to two opportunities to resend the data before discarding the data and declaring a transmission error.
Scan the following barcode to enable ACK/NAK.
If this does not resolve the issue, please reset the barcode scanner or contact us. Click here to find your barcode scanner model and perform the reset.
