KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
3 Overview
The TP-141 and TP-142 are a high-immunity, extended-range twisted pair
transmitter and receiver for computer graphics video and unbalanced stereo
audio signals.
The TP-141 converts computer graphics video and audio inputs to twisted
pair signals, and the TP-142 converts the twisted pair signals back into
computer graphics video, unbala nced stereo and S/PDIF digital audio
signals. Together the TP-141 and TP-142 form a computer graphics
video/audio line transmitter/receiver system.
More specifically, the products feature:
• Highest immunity from any kind of interference
• Resolution exceeding UXGA
• HDTV compatibility
• Simultaneous unbalanced stereo and S/PDIF (24-bit 48kHz) audio
outputs (TP-142)
• Level (gain) and EQ (peaking) controls (TP-142)
• System range up to 250m (750ft)
• Power Connect™ System - Only one unit in a system, the transmitter or
the receiver, needs to be connected to a power source when the devices
are within 50m (150ft) of each other
Note: The TP-141 and TP-142 are not compatible with existing Kramer TP
units such as the TP-121, TP-122, and so on.
3.1 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 suppli es
should be connected to the transmitter and to the receiver simultaneously.
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
