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
