*USB 2.0 spec defines a device in terms of a unit load. A unit load is defined to be 100mA. Devices drawing an absolute maximum of one unit load is considered to be low-powered and devices drawing an absolute maximum of five unit loads is considered to be high-powered. Because this spec is not strictly adhered to, it is best to verify the USB port's power capabilities before operation. This card, according to the USB 2.0 spec, is a high powered device. An optional external power supply can be ordered if the USB port cannot support high powered devices.
If using more than a total of 500mA, use optional 5 VDC external power supply and remove VUSB jumper and place jumper on VEXT. Then plug in external power before plugging into USB port . This option will give you a total of 1000mA available.
