When data is scanned, the data is sent to the host system via the base unit.
Confirmation from the host system or the base indicates that the data sent was
received by the host. The cordless scanner recognizes two forms of host
confirmation: data acknowledgement (ACK) from the base unit or an “ACK” from
the host system. If it cannot be determined that the data has been properly sent
to the host system, the scanner issues an error indication. You must then check
to see if the scanned data was received by the host system.
Acknowledgement from the Base
If the cordless system is configured for a keyboard wedge host interface, a signal
(ACK) is sent from the base confirming that the data was received and is being
sent on to the host system. (Since keyboard wedge interfaces cannot provide
bi-directional communications, they do not permit host confirmation.)
