4 TP-121/3/5EDID, PT-110EDID - Overview
3.2 About the Power Connect™ Feature
The Power Connect feature applies as long as the cable can carry power. This
feature is available when using STP cable and the distance does not exceed 50m
(164ft) on standard CAT 5 cable. For longer distances, heavy-gauge cable should
be used (TP cable is still suitable for the video/audio transmission, but not for
feeding power at these distances). For units that are connected via RJ-45
connectors, make sure that the shield of the STP cable is connected to the metal
casing of the connectors on both ends of the cable. For units that are connected
via terminal block connectors, the shield of the STP cable must be connected to a
ground terminal on the units at both ends. (Use the ground terminal of the power
supply connection if necessary.) For a TP cable exceeding a distance of 50m,
separate power supplies should be connected to the transmitter and to the
receiver simultaneously.
3.3 About EDID
The Extended Display Identification Data (EDID) is a data-structure provided by a
display, to describe its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the product to “know” what kind of monitor is
connected to the output. The EDID includes the manufacturer’s name, the product
type, the timing data supported by the display, the display size, luminance data
and (for digital displays only) the pixel mapping data.
EDID is defined by a standard published by the Video Electronics Standards
Association (VESA).
