6 TP-45EDID - Overview
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 Defining 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 TP-45EDID 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).
