Activity LEDs for Downstream Ports: These 4 LED indicators
are blinking whenever the USB ports are transferring data.
Upstream Port Connector: Type-B connector from upstream
USB2.0 port. It is connected from host or another USB2.0
hub.
Self Power Input Connectors: This 3-pin (one pin plus voltage
and the other 2 pins are GND) terminal block connectors
are used to connect strong power to self-power the hub,
the voltage can be in the range from +7V to 24VDC.
Warning!!
Please make sure the polarity of the input power should be
correctly match the terminal block pins, otherwise it will
damage the hub.
1. Use static electricity discharge precautions.
Remove possible static discharge potential from any
objects that the hub may come in contact with before
installation. This can be accomplished by touching a bare
metal chassis rail after you have turned off the power.
2. Apply DC power (range from +7V to 24V) to the 3-pin
Terminal Block Connector. The hub was bus-powered by
the upstream USB port, this terminal block connector is to
add power to ensure enough power for the 4 downstream
ports.

3. Connecting USB Host cable: The host cable is a standard
A-to-B USB2.0 cable. Please connect the type-A end
connector of the cable to your upstream USB port, then
connect the type-B end connector to this hub. Since the
USB hub is plug-and-play, you don’t have to turn off your
host computer when installing the hub.
Note: In some cases, you will see an error message said
that the USB Hub caused the USB bus power over the current limit,
please ignore this message since the hub is hot plug and its power
capacitor will cause a very short period of current. It will NOT affect
your USB function.
4. Connect the USB devices to the downstream ports of this
hub.
5. Mount your hub on the wall or DIN RAIL if required.
To check the USB hub installation in Windows device manager,
