Power
+5VDC:
60mA (All inputs, no load)
150mA (All outputs low, no load) provided via USB at up to 500mA**
**+5 VDC from the USB bus or external power supply depending on user
configuration. The USB bus is specified to provide 500 mA to most desktop
environments. This gives you 350mA available (500 mA - 150mA = 350 mA).
If using more than a total of 500mA, use optional Regulated 5 VDC external
power supply and remove VUSB jumper and place jumper on VEXT. Then
plug in external power before plugging into USB port.
