Model UH-2D

Note about Twisted-Pair Cables
The UH-2D is designed for operation with standard Cat6 cables (TIA/EIA 568B
wiring). You can use Cat5e cables also if the distance between sender and receiver is
90 ft or less. Shielded Cat6 (STP) can also be used; in fact, STP cables offer the best
performance and provide immunity to poor grounding or external noise. Avoid using
Zero-skew or low skew cables. The low skew cables work well for analog video
extension, but are suitable for digital signals
3. Troubleshooting
Both the sender and the receiver have LED status indicators that can assist you in determining the
causes of potential problems.
Sender Receiver
Figure 3 – LED indicators
On both sides POWER indicated that the UH-2D circuit has power. If either side’s power indicator is
off, you need to check the power supply connection.
On both sides DISPLAY indicates that the UH-2D is detecting a connected display (Hot Plug
Detection). If it is off, the HDMI connection from the Receiver to the LCD is problematic, or the LCD
needs to be turned on.
On the Sender there is a SOURCE indicator, this means that the video source is on (checks 5v
coming from the source). On the Receiver there is a VIDEO indicator, this means that the video
clock is being detected and proper video signal is being received and sent to the LCD.
There are no field serviceable parts in the device. If you think that the device is malfunctioning,
please first try the following steps:
 Check to make sure you haven’t crossed the 2 Cat6 cables
 Check the video connections
 Unplug the power supply and re-attach it
