2.1 Using External Power
U22-160 draws power from the computer to serve the remote
end devices. When devices connected to the remote end require
more power the voltage drop in the cable may become an issue.
The U22-160 includes an external power supply to serve this
additional power requirement, which should be used at the
Remote end.
3. Troubleshooting
If PC fails to detect the USB device, check the LED status on the
Remote unit. Plug the power supply if needed. Cat6 cable is
recommended particularly if the length is longer than 100 ft.
Reboot the Host PC. Connect to a different USB port on the PC.
Try connecting an external hub to the remote unit and plug the
device to the hub.
There are no field serviceable parts or circuits in the device.
Opening the device will void the warranty. If you think the device
is malfunctioning, please contact Hall Research.
