symbology trying to
be scanned is not
enabled.

LED stays on. The scanner is
configured to support
some form of host
handshaking but is
not receiving the
signal.

ACK/NAK, RTS/CTS, XON/XOFF
or D/E, verify that the host cable
and host are supporting the
handshaking properly.
The unit scans,
but the data
transmitted to
the host is
incorrect.
The scanner’s data

format matches that required by
the host. Most sure that the
scanner is connected to the
proper host port.
