Industrial 4 Port USB Hubs
Models UHR204 & UHR304
1. Unpack the USB hub from the shipping container.
Verify that all included items are present.
Note: There is no software CD for this product. It
will install as a Generic USB Hub and does not
require additional drivers.
2. Mount the product via the included DIN clip or included
Panel Mount adapter kit. See the Mounting section for
more information.
3. Using the included USB cable, connect one end of the
cable to the Host PC or upstream USB hub. Plug the
other end of the cable into the USB hub via the port
marked USB Host.
Note: If the USB upstream device is capable of
supplying power to the Hub, then the Bus Power
LED will light. When Local (external) power is
applied to the terminal block or the barrel jack the
Local Power LED will light. The Local Power LED
will light only when power is applied externally and
an active upstream connection is made (normally
needs 500mA from host minimum).
4. Ground the hub to earth ground using the green ground
screw.
5. Add power via the terminal block or barrel jack if one of
the following instances will occur:
Power Scenario 1
The USB hub is connected to an upstream port that
does not offer full power out. (Example: connecting the
B&B hub into another hub that is not externally powered
Power Scenario 2
The USB Hub will have another USB hub connected to
one of its downstream ports.
Power Scenario 3
The USB Hub will have bus powered devices plugged
into it. (Example: using a B&B USB to serial device that
uses the USB bus for power.)
