Power

•

Basic unit: 60mA typical (no load); 12mA with max counter transitions

•

+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 440 mA available (500mA -60mA = 440mA). If using more than

a total of 500mA, use optional 9 VDC (on board voltage regulator outputs +5

VDC to card) 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.

•

+5V resettable fuse at 0.5A located on connector
