3.3 Defining the EDID
The Extended Display Identification Data (EDID
1
3.4 The Power Connect™ Feature in the VP-8x8TP
) 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 PC or laptop 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.
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 (CAT 5 cable is still suitable for the video/audio transmission, but not for
feeding the power at these distances). For units which 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 which 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 CAT 5 cable exceeding a distance of 50m, separate power supplies should be
connected to the receivers simultaneously.
Note: The transmitter can supply power to the receiver but not visa versa.
