1.2 Connector Layout
Figure 1
Power LED: Indicates the hub is powered either by Bus-Power or Self-Power.
Self Power Input Connector: This 2-pin (one pin is + voltage and the other is GND)
terminal block connector is used to connect a wide range power source to self-power
the hub. The voltage can be in the range from +7V to 24V DC.
USB-B Upstream Port USB Downstream Port Self-Power
The Type-B connector from
upstream USB 3.1 port is
connected from the host or
another USB 3.1 Hub’s
downstream facing port.
The downstream facing
port connectors are USB
3.1 Gen1 compliant able to
transfer up to 5Gbps of
data.
Using the included power
supply the hub can be self
powered via its barrel
connector, Can also be
powered through the 7-24V
2-pin terminal block
connection.
1.3 Hardware Installation
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 2-pin Terminal Block
Connector. The hub is self-powered by the upstream USB port (USB-B
connector), This terminal block connector is to add power to ensure enough
power for the 4 downstream ports.
3. Connecting USB Host cables: The host cable could be either a standard B to
A or B to C USB 3.1 cable (depends on the host port’s connector type). Please
connect the Type-A end connector of the cable to your PC’s host USB 3.0
port, then insert 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.
4. Connect the USB Devices to the downstream ports of this hub.
5. Mount your hub on a flat surface such as a wall or tabletop if required.

2. Notes, Tips, and Warnings
Note
In some cases, during hardware installation, 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.
