Notice
1.
If the DVI or HDMI™ device requires the EDID information, please use EDID Reader/Writer to retrieve and provide
EDID information of the DVI or HDMI™ display.
2.
All HDM™I over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP cable and
ASTRODESIGN Video Signal Generator VG-859C.
3.
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 300m or 1,000ft bulk cables) can
transmit a lot longer signals than stranded UTP cables (usually in the form of fixed length patch cords). A solid UTP
Cat-5e cable shows longer transmission range than a stranded STP Cat-6 cable. For long extension applications, solid
UTP/STP cables are the only viable choice.
4.
EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for better performance.
5.
To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, shielded STP cables are
better suited than unshielded UTP cables to improve EMI problems, which is worsen in long transmission.
6.
Because the quality of the CAT-5/6 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.
7.
If your HDMI™ display has multiple HDMI™ inputs, it is found that the first HDMI™ input [HDM™I input #1] generally
can produce better transmission performance among all HDMI™ inputs.
8.
Wrongly inserted IR blaster and IR receiver to wrong 3.5mm infrared sockets may result in the failure of the IR
extenders. Please check carefully before plugging in the IR extender to the respective IR sockets.
