BUS POWER

Bus power requirements

The MicroBook draws all the power it 
needs from the USB bus connection to 
the computer. However, the USB 
connection to the computer must meet all 
of the requirements discussed below.

USB adapter products must be powered

If you are using a USB adapter or hub (a 
third-party product that supplies one or 
more USB ports to your computer), it 
must have direct access to a power 
supply:

■

PCI USB cards

 — If you plan to 

connect the MicroBook to a PCI card and 
run the MicroBook under bus power, the 
PCI card must have a direct connection 
to the power supply harness inside your 
computer. This is the same power supply 
harness to which you connect internal 
hard drives, CD/DVD drives, etc.

■

PCMCIA, Cardbus or ExpressCard 

slot adapters

 — If you plan to connect 

the MicroBook to a PC card, Cardbus or 
ExpressCard USB adapter (inserted in 
the card slot in your laptop), it must 
provide a powered connection and it 
must also have its own power supply. 
Most commonly, these types of products 
have a DC power adapter that plugs into 
an AC wall outlet. As you can see, 
however, this situation does not allow for 
remote battery operation, as the card 
adapter requires AC.

Examples of bus- powered operation

Here are a few typical examples of bus-
powered MicroBook operation:

Bus power from a desktop computer

Your desktop computer is running off of 
its usual AC power connection, and the 
MicroBook draws power from the USB 
cable connected to the computer. There 
are no limits to running time.

Bus power from an AC-powered laptop

This scenario is identical to the desktop 
situation described above: the laptop is 
powered by AC, the MicroBook is 
powered via the USB bus and there are no 
limits to running time.

Bus power from a battery-powered 

laptop

The laptop is being powered by its own 
battery, and the MicroBook is being 
powered by its USB connection to the 
computer, so the laptop battery is 
supplying power to both the laptop and 
the MicroBook. This is the most compact 
and portable operating scenario. 
Running time is determined by the 
capacity of the laptop battery. For 
extended recording sessions, bring extra, 
fully charged laptop batteries.
