Camera Link cable ordering information.

68-Pin VHDCI Cable Specifications

National Instruments offers cables and accessories for connecting to video
sources, trigger sources, or synchronization sources. However, if you want
to develop your own cable for the 68-pin VHDCI connector, you must use
twisted pairs for each signal.
If you are using the IMAQ D6826 breakout cable, refer to Figure B-1 for
the MDR 26-pin medium configuration Camera Link connector pinout.
Refer to Figure B-2 for the 25-pin D-SUB trigger connector pinout.
Note Refer to the following connector pinouts only if you are using the IMAQ D6826
breakout cable. If you are not using this cable, refer to Chapter 4, Signal Connections,
for the standard MDR 26-pin connector pinout.
