1) Set up the hardware, which means supplying the board with +5V, -5V, a Byte-Blaster cable to the PC, a cable to the NI board, and a cable with a TTL pulse on it going to the Test Pulse input. 2) Don't change any defaults - either hardware jumpers or software settings. 3) Power on the board. It should draw about 0.7 A on the +5 supply. 4) Bring up a DOS window on the PC, go to the jam_tdc directory, and type jam_tdc.exe -aconfig_basic TDIG.jam This sets up the HPTDC and the current on the +5V supply should increase ~0.1 A. 5) Type jam_tdc.exe -astatus TDIG.jam This checks the TDC status (three of the bits should be 1, the rest should be 0). 6) In the LabVIEW folder, run HPTDC_ReadSinglesAndCoinData.vi You should get a nice, narrow time difference peak
