DVI-TP-TX200DL/RX100DL
User’s Manual Rev. 1.0

The DVI standard maximizes the data rate of the TMDS channels in 1.65 Gbps.
Dual link DVI interface enables a higher resolution compared to single link
transmission by doubling the number of wire pairs to transmit the video signal. In
single link cables 3 wire pairs carry the color information (red, green and blue) and
one wire pair carries the clock signal (TMDS clock). In dual link cables, 6 wire pairs
carry the color information next to the TMDS clock signal. One color component is
carried by two wire pairs, where one wire pair carries the odd pixels and the other
wire pair carries the even pixels.

Info The colors of the wire pairs in the picture represent the color information they carry
and not the color of the actual wires inside the cable.
2.8. Fiber Cable powering
As a special feature, both DVI-TP-TX200DL (MONITOR OUTPUT) and DVI-TP-
RX100DL (DVI OUTPUT) are able to supply 500 mA current to power fiber optical
transmitters like Lightware DVI-OPT-TX100 (Pin 14 on DVI OUT connector).
Standard DVI outputs or VGA cards supply only 55 mA current on +5V output, thus
unable to directly power a fiber optical transmitter.
Info DVI-TP-TX200DL and DVI-TP-RX100DL do not check if the connected sink
(monitor, projector or other equipment) supports Hotplug or EDID signals but
outputs the input signal immediately after it has been applied to the input.
