UHBX-8X

The Front panel of the UHBX-8X provides LED indicators for both the AC
and the optional 48 vDC power inputs.

4.0 Operation
Once all the input and output connections are made as described in the
previous section, connect AC power to the UHBX-8S. There is no separate
on/off switch, so application of AC power will turn the unit on. Verify power
supply operation on the front panel indicators. If a UHBX-R-PD is used as the
receiver (needs PoH), make sure the optional 48V power supply is connected
to the sender and the 48V DC light is lit on the front panel.
In compliance with HDBaseT Alliance recommendations, the UHBX-8X
performs IEEE802.3af low-voltage handshake prior to inserting 48v onto the
Cat6 cables. This process can take up to 3 seconds. Once PoH is successfully
sent to each receiver the PoH LED on the front panel (and on the Receiver)
will be lit. When the Link LED on Sender and Receiver are lit (or blinking)
the system is ready to extend video and if you have source video connected, it
should be visible on the remote displays.
If you are using UH-1BTX receivers and want to extend beyond the 100meter
range, or if you are having video blanking issues (due to inferior UTP cable or
electrical interference), you can set the HDBaseT mode of any of the 8 outputs
to Long Reach using the Windows GUI software.
Also since HDBaseT has limitations regarding sending RS-232 and IR signals
in low power mode, when connected to receivers that have IR or RS-232 (such
as UHBX-R-PD), the UHBX-8X keeps the HDBaseT link fully active at all
times even if there is no video. If you are using UHBX-R-PD as receiver, but
are not using the RS-232 nor the IR functions, it is recommended that you turn
on “power management” using the GUI. This will cause both the sender and
the receiver to go into low power mode if no display is detected or if there is
no video input. The HDBaseT chipsets consume only a fraction of power
when they are in low power mode.
