8-Port HDMI Extender with Power, IR, and RS-232

6.0 Troubleshooting
If you are experiencing problems getting the extender to work properly, please
use the following troubleshooting suggestions.
a.
Make sure that all of the connections on both the sender and the receiver
are solid. Loose connections are the number one cause of issues.
b.
Try resetting the system by unplugging the power supply connected to the
sender, waiting 5 seconds and plugging it back.
c.
Check the state of the LED’s on the front of both the sender and the
receiver. Refer to the table in section 4 to interpret the status being
indicated.
d.
If the cable length is longer than 100 meters (330 ft), then you must set
the HDBaseT mode to "Long Reach". If you are using UHBX-R-PD then
you should set the mode using the little slide switch on the receiver
(below the HDMI output connector) to L.R. (Long Reach). If you are
using UH-1BTX-R receiver which does not have a mode switch, then you
have to set the mode on the UHBX-8X using the GUI via the USB
connection. If you are using an HDBaseT Class B (lite) receiver such as
the model UH-1BT-R, then you cannot set the mode to Long Reach since
the Class B devices do not support this mode
e.
In L.R. mode the unit does not support deep-color, nor 4Kx2K video. So
you have to make sure your source does not output video with deep color
or 4K (UHD) video.
f.
Make sure the display is compatible with the video source by connecting
them directly.
g.
Make sure that the UTP or STP cable meets the requirements. Never use
low-skew cable for digital video extension (low skew cables are suited for
analog video extension, but do not work well for digital video). Read
section 3.2.6 for UTP cable requirements.
h.
The extender requires that the source DDC signals of its HDMI output
operate at100 KHz or less and support clock-stretching. The vast majority
of sources meet these requirements. But if you determine that a particular
source does not (by substituting a video pattern generator, or a different
source), an HDMI transceiver may be needed. Hall Research offers the
model EMX-HD-AUD that has a compatible output, can handle virtually
any HDMI input, and has proven its ability to resolve source
incompatibility issues.
