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 milliamp s, 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.
