Maintenance, Troubleshooting & Technical Specifications 3 - 5
Digital scanner decodes bar code,
but does not transmit the data to the
host.
Digital scanner is not programmed for
the correct host type.
Scan the appropriate host type
programming bar code. See the chapter
corresponding to the host type.
Interface cable is loose. Re-connect the cable.
If the digital scanner emits 4 long low
beeps, a transmission error occurred.
This occurs if a unit is not properly
configured or connected to the wrong
host type.
Set the scanner's communication
parameters to match the host's setting.
If the digital scanner emits 5 low beeps,
a conversion or format error occurred.
Configure the digital scanner's conversion
parameters properly.
If the digital scanner emits low/high/low
beeps, it detected an invalid ADF rule.
Program the correct ADF rules. Refer to
the Advanced Data Formatting
Programmer Guide.
If the digital scanner emits high/low
beeps, the scanner is buffering Code 39
data.
Normal scanning a Code 39 bar code and
the Code 39 Buffering option is enabled.
Host displays scanned data
incorrectly.
Digital scanner is not programmed to
work with the host.
Scan the appropriate host type
programming bar code.
For RS-232, set the digital scanner's
communication parameters to match the
host's settings.
For a Keyboard Wedge configuration,
program the system for the correct
keyboard type, and turn off the CAPS
LOCK key.
Program the proper editing options (e.g.,
UPC-E to UPC-A Conversion).
Digital scanner emits short low/short
medium/short high beep sequence
(power-up beep sequence) more
than once.
The USB bus may put the digital
scanner in a state where power to the
scanner is cycled on and off more than
once.
Normal during host reset.
Digital scanner emits 4 short high
beeps during decode attempt.
Digital scanner has not completed USB
initialization.
Wait several seconds and scan again.
Digital scanner emits
Low/low/low/extra low beeps when
not in use.
RS-232 receive error. Normal during host reset. Otherwise, set
the digital scanner's RS-232 parity to
match the host setting.
Digital scanner emits low/high beeps
during programming.
Input error, incorrect bar code or
Cancel
bar code was scanned.
Scan the correct numeric bar codes within
range for the parameter programmed.
