IV. Power Mode Setting
There are two power mode options for the USB 2.0 4-Port TetraHub™.
The first is bus-power mode, which does NOT require the use of anAC
power adapter. In this mode, the hub is provided with 500 milliamps for
all 4 ports. This should be adequate for mice, keyboards, and other low
power devices.
The second is self-power mode, which requires the use of an AC power
adapter. In this mode, each port is provided with 500 milliamps, allowing
for additional hubs, cameras and other high-powered devices.

How do you know which power mode is right for you? Most applications
do not require an AC power adapter. If you have high powered devices
connected, your computer may display an error message indicating the
hub has insufficient power to support the connected devices. This will
indicate that an AC power adapter is necessary for your application. If
you are not sure or if device performance is poor, use the AC adapter.
An AC adapter can be purchased from our website for $9.99 plus
shipping and handling. For more information, please visit:
http://www.jascoproducts.com/hubpowersupply.html
When using the AC power adapter, make sure the plug is properly
connected to the hub and to a standard electrical outlet. GE Surge
protection is recommended.
