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.)

USB bus powered option (UHR204 only)
The hub can be USB bus powered. When USB bus
power is used the amount of power available to each
of the USB downstream ports is limited to 100mA
maximum per port.
External power option (UHR204 and UHR304)
10 to 30VDC, 16 watts maximum, Class 2 Input
Terminal Block or Locking Power Jack
Note 1: When external power is used the hub will provide
up to 500mA per downstream port.
Note 2: The terminal block input and the locking barrel jack
are wired so that both can be powered at the same
time. This is a great option to achieve power
redundancy.
DIN Rail Mounting
1. To install locate the included DIN rail mount kit which
includes the bracket and 3 installation screws.
Note: The DIN rail mounting bracket can only be
installed on the back side of the hub.
2. Find the 3 mounting holes located on the back side of
the hub and install the mounting bracket with the flat
surface facing the back of the hub with the included
mounting screws.
3. The product is now ready to be mounted on a piece
of DIN rail.
Panel Mounting
1. To install locate the included panel mount kit which
includes two bracket pieces and 4 installation screws
(2 screws per bracket).
Note: The Panel Mount Brackets can be mounted
to either side of the product and allows mounting
Up, Down, Forward and Back.
2. Using the 4 screws (2 per bracket) attach the
brackets to the hub. The shorter side of the bracket
in which the holes are close together is the side that
will mount to the hub. The bracket when installed
correctly will form an L shape with the side of the
hub.
3. Once the brackets are installed the product is ready
to be mounted.
Power input: 10 to 30 VDC, 16W maximum, Class 2 Input
Surrounding Air Ambient Temperature: -40 to 80° C
