This section describes the TP-125EDID XGA/Audio/Data Line Transmitter.
6.1 Overview
The TP-125EDID is a high-performance XGA/stereo audio line transmitter. It
inputs an XGA signal (up to WUXGA, 1080p), unbalanced stereo audio signal, and
bidirectional RS-232 control commands and transmits them over CAT 5 cable to a
receiver (for example, the Kramer TP-126 UXGA/Audio/Data Line Receiver). It
converts the unbalanced stereo audio signal to a digital audio (S/PDIF) stream
before transmitting, to preserve the quality of the audio signal. Commands and
data can flow in both directions via the RS-232 interface, allowing status requests
and control of the destination unit. The TP-125EDID includes H and V Sync
internal polarity switches.
When the TP-125EDID is connected to a display device and the EDID CAPTURE
button is pressed, the TP-125EDID reads and stores the EDID (Extended Display
Identification Data) from the display device. The display can be disconnected and
later reconnected without rebooting the operating system.
The TP-125EDID features:
•
A maximum resolution of WUXGA and 1080p
•
A transmission range of more than 300ft (100m), and a 20kHz audio
bandwidth with an S/N ratio that exceeds 80dB on the same
transmission range
•
A bidirectional RS-232 port where commands and data can flow in both
directions via the RS
−232 interface, allowing status requests and control of
the destination unit
•
EDID Capture that copies and stores the EDID from a display device
•
12V DC power
