>Outside size and shape is the same as a standard 15 pin D-sub >(joystick cable) but inside it has 5 "standard" size pins and >2 (one on each end) larger high current pins- picture attached. These are a standard D connector. The large pins can be either high current pins or coax connectors. In the UK available through RS Components, but any Cannon wholesaler should be able to source them for you. I imagine Digikey will have them. -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
