1) Connect B-type plug
(square connector) to ‘PC connect’ side of the USB
Isolator.
2) Connect A-type plug of USB cable to an available USB port on the
computer (the power LED will turn on when connected to a powered
computer).
3) Connect the A-type plug
(flat connector) to the ‘device connect’ side of
the isolator. Connect the other side of the cable to the peripheral being
isolated.
NOTE:
This device is not intended to isolate the trunk of a
USB hub, as its output current is limited to ~137mA.
4) Your computer should prompt that a new device has been connected to
the computer. The power LED of the isolator should be ON and not
blinking. At this point, you are ready to begin talking to your connected
device.
TIP:
If your PC fails to detect your USB device, try pushing the reset
connection button on the Isolator.

Note:
This device is not
intended to isolate hubs.
Note:
This isolator will break
the path to earth ground. Most
personal computers connect
the USB signal ground in
common with the cable shield
and earth ground. The PC
connector side of this isolator
also holds signal ground in
common with the connector
shield. The target device
connector side of this isolator
does not transfer the earth
ground connection across the
barrier that was made at the
PC side. If the device that you
are isolating must be earth
grounded, other provisions
must be implemented to
introduce earth ground to the
isolated side.
