NOTICE:
1. When adjusting the signal level on the receiver unit, please dial the rotary control switch from MIN to MAX and
stop turning the rotary switch whenever the audio/video is playing normally. Inappropriate signal level setting may
cause overpowering issue that would shorten the product life significantly!
2. If the DVI or HDMI TM device requires the EDID information, please use AT-DVISync EDID Reader/Writer to retrieve
and provide DVI or HDMI TM display EDID information.
3. All HDMI TM over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP cable and
ASTRODESIGN Video Signal Generator VG-859C.
4. The transmission length is largely affected by the type of Cat-5/5e/6 cables, the type of HDMI TM sources, and
the type of HDMI TM display. The testing result shows solid UTP cables (usually in the form of 300m [1,000ft] bulk
cables) can transmit a lot 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 Cat-5e cable shows
longer transmission range than stranded STP Cat-6 cable. For long extension applications, solid UTP/STP cables
are the only viable choice.
5. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended.
6. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one can use double
shielded STP cables to improve EMI problems, which is worsen in long transmission.
7. Because the quality of the category cables has the major effect on how long the transmission limit can achieve
and how good is the received picture quality, the actual transmission range is subject to one's choice of Cat-5/5e/6
cables. For desired resolutions greater than 1080i or 1280x1024, a Cat-6 cable is recommended.
8. If your HDMI TM display has multiple HDMI TM inputs, it is found that the first HDMI TM input [HDMI TM input 1] generally
can produce better transmission performance among all HDMI TM inputs.
