Connecting the External Power Supply

If the peripheral devices connected to the HUB4 require more power per port than the
100 mA that is provided through the computer or if you want to drive an additional device
from the same power source, you can attach an Extron PS 1210 C external 1 A, 12 VDC
power supply to the hub to increase the power to 500 mA per port.

NOTE: Do not splice or extend the USB cable connecting the host
computer to the HUB4 beyond 15 feet (4.5 meters). Extending it
further than this can cause USB communication to fail.
Connecting the PC to the USB Captive Screw Connector
It is recommended that you use a 12 VDC external power supply if planning to use
flash drives or Web cams, because those devices typically require greater than
100 mA.
If only a keyboard and mouse are being powered, 100 mA is usually sufficient.
Use only the Extron PS 1210 C power supply with the USB HUB4.
