4 HARDWARE SPECIFICATION
4.1 POWER REQUIREMENTS
All parameters @ 20°C unless stated
Supply Voltage via USB: 5.0V from host computer
Supply Voltage via optional: 7.5V from mains power adapter
external power input
Supply Current (active): 50mA
Supply Current (suspend): 1.5mA
The maximum current that can be drawn from the USB bus 500mA. Therefore the
PCMCIA card cannot consume more than 450mA.
If more current is required, the optional external power connection must be used.
However, the total current drawn through the external power input must not exceed
750mA. Hence, the PCMCIA card cannot consume more than 700mA.
Note: A mains adapter is not supplied with the USB reader.
4.2 MECHANICAL
