serial port, allows quick programming of the device parameters
(upload and download of a parameter map to or from one or
more devices of the same type). The upload (label UL), download

Copy Card
Download reset: connect the key with the device OFF. When the
device is switched on, the programming parameters are loaded
into the device. After the lamp test, the display shows the
following for about 5 seconds:
• label dLY, if the operation is successful
• label DLn otherwise
• The FPr folder, located in the USEr level of the
programming menu, contains the commands
necessary for using the CopyCard. Press the "Set"
key to access the functions.
• Scroll with the "UP" and "DOWN" keys to find
the desired function. Press the "Set" key to
execute the desired function (upload, download
or formatting).
