Chapter 5: Performance Notes
5. Performance Notes
1. When you adjust the signal level on the receiver, dial the rotary control switch
from 7 to 0 and stop turning the rotary switch whenever the audio/video is
playing normally. Inappropriately setting the signal level might damage the
extender.
playing normally. Inappropriately setting the signal level might damage the
extender.
2. If the DVI or HDMI device requires the EDID information, use the EDID reader/
writer to retrieve and provide DVI or HDMI display EDID information.
3. The transmission length is largely affected by the type of CAT5/5e/6 cables,
the type of HDMI sources, and the type of HDMI display. The testing result
shows solid UTP cables (usually in the form of 1000 ft. [300 m] bulk cables)
can transmit much longer signals than stranded UTP cables (usually in the
form of fixed length patch cords). Shielded STP cables are better suited than
unshielded UTP cables. A solid UTP CAT5e cable transmits farther than
stranded STP CAT6 cable. For long extension applications, use solid UTP/STP
cables.

4. We recommend using EIA/TIA-568-B termination (T568B) for CAT5/5e/6
cable.
5. To reduce the interference among the unshielded twisted pairs of wires in
CAT5/5e/6 cable, use shielded STP cables to improve EMI problems.
NOTE: EMI problems are more common in long transmission.

6. Because the quality of the CAT5/5e/6 cables has a major effect on how long
the transmission limit can be and how good the received picture quality is,
the actual transmission range depends on which CAT5/5e/6 cables you
choose. For desired resolutions greater than 1080i or 1280 x 1024, we
recommend using CAT6 cable.

7. If your HDMI display has multiple HDMI inputs, the first HDMI input [HDMI
input #1] generally can produce better transmission performance among all
HDMI inputs.
