The home page of the CFDL1 is located at http://www.tellert.de/?product=cfdl1.
Adjustment of the real time clock: The CFDL1 must be connected via a USB cable with a type B plug (and not with the virtual COM port USBSER). Then, there must be a parameter set running on the CFDL1 (meaning a CF card with a valid parameter set is inserted in the CFDL1). The synchronize process is then started with TEMES → Tools → Additional Tools → Hardware → Set CFDL1 real time clock. When the CFDL1 cannot hold the real time after a power cycle, then keep the CFDL1 on power for at least 2 hours.
CF card initialization: The initialization of a CF card is done with TEMES → Tools → Additional Tools → Hardware → Initialize CF card (CFDL1).
Display remains empty (while turning the power switch): Please verify whether the device is connected to a power supply. The RS232/USB connector does not supply the device with (enough) current.
