TP transmission
The TP output on the RJ-45 connector and an optional Extron VTR001CM receiver
provide a system for long-distance distribution of computer (RGBHV or RGBS)
video over Extron’s skew-free A/V UTP cable or over CAT 5 unshielded twisted
pair (UTP), shielded twisted pair (STP), or foil shielded twisted pair (FTP) cable.
The VTR001CM can receive RGsB signals from the scaler. However, the red,
green, and blue video signals’ black levels are not clamped to a 0V reference, as
for RGBHV or RGBS. For most displays, this is not a problem. On some
displays (such as some LCD displays) however, the black levels of the red,
green, and blue signals may change as the average picture level changes,
resulting in an unacceptable image.
TP cable advantages
Extron’s skew-free cable or CAT 5 cable is a fraction of the size of coaxial cable, as
well as being much lighter, more flexible, and far less expensive. These TP
products make cable runs simpler and less cumbersome. Termination of the cable
with RJ-45 connectors is simple, quick, and economical.
