NOTICE
1. When adjusting the signal level on the receiver unit, please dial the rotary control switch from 7
to 0 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 device requires the EDID information, please use EDID Reader/Writer to
retrieve and provide DVI or HDMI display EDID information.
3. All HDMI over Cat.X transmission distances are measured using Belden 1583A CAT5e 125MHz
UTP cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
4. The transmission length is largely affected by the type of Cat-5/5e/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 330m 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 category 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 CAT5/6 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 display has multiple HDMI inputs, it is found that the first HDMI input [HDMI input
1] generally can produce better transmission performance among all HDMI inputs.
