There can be many reasons for communication problems:
The communication port configuration is not correct. The configured
communication port is not the COM port which is actually used.
The baud rate between the computer communication port and the DIGIgarde
PLUS are different.
DIGIgarde PLUS is not connected to a power source or the computer.
DIGIgarde PLUS has not completed its startup procedure.
The serial number of a linked terminal is not correct.
There is a problem with a data line or converter.
The computer COM port is broken. Try testing it with another device.

After prolonged use, the surface of the fingerprint sensor may become dirty or
scratched. The DIGIgarde PLUS may sense the dirt and scratches as a fingerprint
and attempt verification. Alternatively, a connecting cable may be loose or there
could be an internal problem.
Clean the sensor window with some adhesive tape and a soft cloth (see page 55).
Check all connections.
If the problem remains, please contact your supplier.
