This section describes the TP-123EDID XGA/Audio/Data Line Transmitter.
5.1 Overview
The TP-123EDID is a high-performance XGA/stereo audio line transmitter. It
inputs an XGA signal (up to WUXGA, 1080p), unbalanced stereo audio signal, and
unidirectional (RxD) RS-232 control commands and transmits them over CAT 5
cable to a receiver (for example, the Kramer TP-124 XGA/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.
When the TP-123EDID is connected to a display device and the EDID CAPTURE
button is pressed, the TP-123EDID 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-123EDID 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 unidirectional RS-232 port for transmitting control commands
• EDID Capture that copies and stores the EDID from a display device
• The Power Connect Feature that transmits power to the receiving
device, or receives power from it, over twisted pair cable
• 12V DC power
