Note about Twisted-Pair Cables
For best results we recommend using Shielded 23 Gage Solid Cat6 cables Unshielded
(UTP) 23 AWG Cat 6 Cable also provides great results and can be used if noise free
environments.
Use TIA/EIA 568B straight through wiring termination. Avoid using Zero-skew or low skew
cables. The low skew cables work well for analog video extension over twisted pair, but
since the UH-2C is a pure digital system, the cross-talk of the low skew cables will actually
shorten the maximum achievable cable length
.
4. Troubleshooting
There are no field serviceable parts or circuits in the device. If you think that the device is
malfunctioning, please first try the following steps:
Check to make sure the 2 Cat6 cables are not crossed.
Check the video connections.
Unplug the power supply and re-attach it.
Check the indicator lights on the unit. If the top LED (REMOTE PWR) for the desired port
is unlit, please verify that the 5v power supply is connected to the receiver (UH-2C-R) and
that the 2 Cat6 cables are connected between the sender and receiver. If the bottom LED
(LCD DETECT) for the desired port is unlit, please verify that the remote LCD is on and
connected to the receiver (UH-2C-R).
Connect the display directly to the source and make sure that an image is present without
the extender. If so, then use the menus of the video source to lower the output resolution
(such as 480p). Insert the extender and verify that you get an image. If so, then set the
resolution to the next higher value (such as 720p). Continue this process until you get the
highest possible resolution without loss of image or audio.
The quality of the cable and the connections
will determine the maximum length and
resolution achievable.
