4.0 Troubleshooting
If you are experiencing problems getting the extender to work properly,
please use the following troubleshooting suggestions.
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.
Try resetting the system by unplugging the power supply, waiting 5
seconds and plugging it back.
Check the state of the LED’s on the front of both the sender and the
receiver. Refer to the table in section 4.5 to interpret the status being
indicated.
If the cable length is longer than 100 meters (330 ft) set the Mode
Switch on the receiver to L.R. (Long Reach) position (see section 4.4).
In L.R. mode the unit does not support deep-color, or 4Kx2K video.
Make sure the display is compatible with the video source by
connecting them directly.
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 3.2.4 for UTP cable requirements.
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 HD-AUD that has a compatible output, can
handle virtually any HDMI input, and has proven its ability to resolve
source incompatibility issues.
If you still are not able to get the system working properly, contact Hall
Research support (preferably via email or the form on support page of
www.hallresearch .com) with a detailed description of the issue and the
troubleshooting steps you have taken.
Do not open or try to repair the unit yourself as this will void your warranty.
To return the extender for repair, you must contact HR Support at 714-641-
6607 or via email or web. To ship the unit back for repair, make sure to
obtain a Return Material Authorization (RMA) number.
