3.2 Defining EDID
The Extended Display Identification Data (EDID
1
3.3 Using Twisted Pair Cable
) 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-575
to
“know” what kind of monitor is connected to the output. The EDID
includes the manufacturer’s name, product type, timing data supported by
the display, display size, luminance data and (for digital displays only) the
pixel mapping data.
Kramer engineers have developed special twisted pair cables to best match
our digital twisted pair products; the Kramer:
BC-DGKat524
(CAT 5 24
AWG), the Kramer:
BC-DGKat623
(CAT 6 23 AWG cable), and the
Kramer:
BC-DGKat7a23
(CAT 7a 23 AWG cable). These specially built
cables significantly outperform regular CAT 5 / CAT 6 / CAT 7a cables.
Note: the
TP-575
cannot work with unshielded cables.
3.4 About the Power Connect™ Feature
The Power Connect™ feature here means that the
TP-575
unit can power
both the transmitter and receiver when they are within 270 feet (90 meters)
of the
TP-575
. The Power Connect™ feature applies as long as the cable
can carry power. The distance does not exceed 90 meters on standard twisted
pair cable, for longer distances, heavy gauge cable should be used

3.5 Recommendations for Best Performance
.
To achieve the best performance:
•
Connect only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and
elevated noise levels (often associated with low quality cables)
•
Avoid interference from neighboring electrical appliances and position
your
TP-575
away from moisture, excessive sunlight and dust

2 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
