Panel Mounting
The panel mount
brackets can be
attached to either side
of the hub. They can be
attached in (4) positions:
Up, Down, Forward
and Back.
USB Power
The non-isolated UHR204 can operate without
an external power supply (USB power-only mode). When
the hub is running on USB power it provides a maximum
of 100 mA to each of the downstream ports.
When an external power supply is used the UHR204
will provide 500 mA to each of the downstream ports.
External Power
Unlike the non-isolated UHR 204, the isolatedUHR304
will not operate without an external power supply.
You can use the detachable terminal block input or the
locking barrel jack. Terminal block is polarity protected.
When powered, the UHR204 and UHR304 will provide
500 mA to each downstream port. They require 10 to
30 VDC external power and will consume a maximum
of 16 W.
We strongly recommend that you ground the chassis.
Connect a grounding wire from the green ground lug
to a good source of earth ground.
