KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
4
Although Unshielded Twisted Pair (UTP) cable might be preferred for long range
applications, the UTP cable should be installed far away from electric cables, motors
and so on, which are prone to create electrical interference.
However, since the use of UTP cable might cause inconformity to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.
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
on standard CAT 5 cable. For longer distances, heavy gauge cable should be
used
1
. 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 transmitter and to the receiver simultaneously.
3.3 Defining EDID
The PT-110-od, TP-121-od, TP-123-od, and TP-125-od include:
• EDID Capture - Copies and stores the EDID from a display device
The Extended Display Identification Data (EDID
2
) 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 graphic source 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.
3.4 Recommendations for Achieving the Best Performance
To achieve the best performance:
• Use only good quality connection cables
3
to avoid 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 that may adversely
influence signal quality and position your Kramer transmitters away from
moisture, excessive sunlight and dust
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
