11. Notice
1. All HDMI over CAT5 transmission distances are measured using Belden 1583A CA -
T5e 125MHz UTP cable and ASTRODESIGN Video Signal Generator VG-859C & VG-
870B.
2. Incorrect placement of IR Blaster and Receiver may result in the failure of the IR
extenders. Please check carefully before plugging in the IR extender to the respec -
tive IR sockets. Warranty will not cover the damage.
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 [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.
4. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for bet -
ter performance.
5. To reduce the interference among the unshielded twisted pairs of wires in Cat-
5/5e/6 cable, one can use shielded STP cables to improve EMI problems, which is
worsen in long transmission.
6. 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 desi -
red 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
[HDMI input #1] generally can produce better transmission performance among all
HDMI inputs.
