Thanks for the info. The ultimarc site says this:
Do I need a power supply?
The board does need a 5 volt supply. A cable is supplied which plugs into the I-PAC board if you have one, to provide this supply. If you are not using an I-PAC board, a 5 volt supply can be obtained from a joystick port, ps/2 mouse port, or any other 5 volt source from the PC.
So, I was kinda going by that. I doulbe check things too.
Mucho thanks.
