Type-B connector from
upstream USB 3.0 port. It is
connected from host or
another USB3.0 hub. The
connector is compatible
with either non-Screw-Lock
or Screw-Lock (optional)
type cables.
There are 4 Type-A
downstream USB 3.0
connectors. They should be
connected to the USB
devices with non-Screw-
Lock or Screw-Lock
(optional) cables.
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 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 USB 2.0
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.

4. Connect the USB devices to the downstream ports of this hub. You can use
either non-Screw-Lock or Screw-Lock type (optional) cables. This hub
supports both USB 3.0 and USB 2.0 devices. Since the USB 3.0 connectors are
capable of plugging in the standard USB2.0 or USB3.0 cable, it supports both
devices directly.
5. Mount your hub on the wall if required.

2. Notes, Tips, and Warnings
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.
