TDC 8000/8001 uses a serial connection to PC. You will need the correct DIN plug for TDC and DB9 for PC. Pin out for the TDC can be found in the TDC manual and for the DB9 is
Pin 2 PC RX (connects to TDC TX)
Pin 3 PC TX (Not needed unless you need Bi Directional comm)
Pin 5 Ground
If you are using laptop with only USB ports you need a USB to serial adapter or other type of serial adapter to receive data from the TDC.
Depending on the software you are using on the PC you can usually get by with only two wires, signal and ground.
