Problem
Bar code is decoded, but data is
not transmitted to the host.
Scanned data is incorrectly
displayed on the host.
Scanner emits short high/short
high/short high/long low beep
sequence when it is not in use.
Scanner emits long low/long high
beep sequence while it is being
programming.
Scanner emits short low/short
high/short low/short high beep
sequence while it is being
programming.

medium/short high beep
sequence after changing USB
host type.

when it is not in use.
Maintenance and Technical Specifications
Possible Causes
Scanner is not programmed for
the correct host type.
Interface cable is loose.
If 4 long low beeps are heard, a
transmission error was
detected.
If 5 long low beeps are heard, a
conversion or format error was
detected.
Scanner is not programmed to
work with the host.
RS-232 receive error.
Input error or 'Cancel' bar code
is scanned.
Out of ADF parameter storage
space.
Out of Synapse parameter
storage space.
The USB bus re-establishes
power to the scanner.
In RS-232 mode, a <BEL>
character is received and Beep
on <BEL> option is enabled.
Possible Solutions
Scan the appropriate host parameter bar
codes.
Ensure all cable connections are secure.
Ensure the scanner's communication
parameters match the host's setting.
Ensure the scanner's conversion
parameters are properly configured.
Ensure proper host is selected.
For RS-232, ensure the scanner'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.
Normal during host reset. Otherwise, ensure
the scanner's RS-232 parity setting matches
the host setting.
Ensure the correct numeric bar codes, that
are within range for the parameter that is
being programmed, are being scanned.
Erase all rules and re-program with shorter
rules.
Scan 'Set Synapse Defaults' bar code, from
the appropriate Synapse Interface Guide,
for cables no longer in use and re-program
the scanner for the current host interface.
Normal when the USB host type is changed.
Normal when Beep on <BEL> is enabled
and the scanner is in RS-232 mode.
