* Connect the green digitizer cable (signal + power)
between the PORT A socket on the DCM and the
DATA connector on the digitizer. Connect a second
digitizer or digital sensor to PORT B if applicable;

the NETWORK socket on the DCM and your network
switch or hub;
* Connect the 9-pin ‘D’ connector on the blue cable
to your PC’s serial (COM) connector;
