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 an AC  
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.  
Page 6  
 
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:  
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.
