We recommend auto-guiding your GOTO mount through the camera and mount ST4 port with the ST4 Cable, which is the grey cable provided with your camera. 
Plug the grey ST4 cable into the camera, and into the mount. Then connect the camera to your PC with the USB cable.
NOTE: Sometimes the very latest cameras aren't yet included in the PHD main release. You can still get them working by copying the altaircam.dll file into the PHD folder like this.
