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 video is playing normally. Inappropriate
signal level setting may cause overpowering issues that would shorten the product’s life
significantly!
2.
All DVI 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 Category cables, the type of DVI
sources, and the type of DVI display. The testing result shows solid UTP cables (usually in the
form of 1000ft 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 category cables is recommended.
5.
To reduce the interference among the unshielded twisted pairs of wires in category cable, one
can use double shielded STP cables to improve EMI problems, which is worse in long
transmission.
6.
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.
