Notes:Notes: The processor does not come with a power cord because most people use the processor with other systems (such as cameras) and therefore use their own shared power cord. If you need a power cord for the processor itself, you can get it from us (look at Part and Accessories tab) at a discounted price $9.99. You can also get extra Female Jack BNC Male Adaptor Connector (see the picture below) at $0.99 each.
