Maintenance and Technical Specifications 3 - 3
Scanner emits four long low
beeps after scanning a bar
code. Cradle has not completed
USB initialization. Wait several seconds and scan again.
Incorrect host interface
cable is used. Ensure that correct host interface cable is used.
Interface/power cables to
cradle are loose. Ensure all cable connections are secure.
Scanner is not paired to a
cradle. Scan the PAIR bar code on the cradle that is
connected to the host that is to receive data.
Scanner has disconnected. See disconnect beep sequence above.
A transmission error was
detected. Ensure the cradle’s communication parameters
match the host's setting.
Bar code is decoded, but data
is not transmitted to the host. Scanner not paired to
host-connected interface. Pair the scanner to the cradle (using PAIR bar
code on the cradle)
Cradle not programmed for
correct host interface Check scanner host parameters or edit options.
Interface cable is loose. Ensure all cable connections are secure.
Cradle has lost connection
to host. In this exact order: disconnect power supply;
disconnect host cable; wait three seconds;
reconnect host cable; reconnect power supply;
reestablish pairing.
Five long low beeps are heard
after a bar code is decoded A conversion error or format
error has been detected. Ensure the scanner’s conversion parameters are
properly configured.
Scanned data is incorrectly
displayed on the host. Cradle host communication
parameters do not match
host’s parameters. Ensure proper host is selected.
For RS-232, ensure the cradle’s communication
parameters match the host’s settings.
For a Keyboard Wedge configuration, ensure the
system is programmed for the correct keyboard
type, and the CAPS LOCK key is off.
Ensure editing options (e.g., UPC-E to UPC-A
conversion) are properly programmed.
Scanner emits short high-short
high- short high-long low beep
sequence when it is not in use. RS-232 receive error. Normal during host reset. Otherwise, ensure the
scanner’s RS-232 parity setting matches the host
setting.
Scanner emits long low-long
high beep sequence during
programming. Input error or ’Cancel’ bar
code was scanned. Ensure the correct numeric bar codes, that are
within range for the parameter being programmed,
are being scanned.
