I need to know what kind of connector I need to look for in order to connect 5v and gnd on the ipac to the optipac. I bought an optipac USB but can't seem to find the USB cable the should have come with it, so I am going to hook it up via serial cable. Since I bought a USB unit I did not get the power connector. Does any one have a picture of what they look like? Is it similar to the connectors used on an ATX case for the power switch, msg ligts ect?
