1.2 Connector Layout
Figure 1
Upstream Port Connector Self Power Input Connector
Type-B connector from upstream USB 2.0
port. It is connected from host or another
USB 2.0 hub.
This 2-pin (one pin plus voltage and the
other pin is ground) 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.
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 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.
5. Mount your hub on the wall or DIN RAIL if required.
