IMAQ D6826 Breakout Cable
This guide describes how to use the National Instruments D6826 breakout
cable to connect the IMAQ PCI/PXI-1428 image acquisition device to a
Medium configuration Camera Link camera and provide connectivity to
the device’s triggering lines.
The D6826 breakout cable converts the VHDCI connector into an MDR
26-pin Camera Link connector for Medium configuration connectivity and
a 25-pin D-SUB connector for triggering.
Getting Started
The following items are necessary for installing the IMAQ D6826 breakout
cable:
❑IMAQ D6826 breakout cable

Triggering
You can use the IMAQ D6826 breakout cable for applications that require
precise triggering or exposure control. The IMAQ D6826 breakout cable
connects the trigger lines on the IMAQ 1428 to the 25-pin D-SUB
connector. You can use these trigger lines to generate precise timing and
triggering for controlling a camera or other devices. You can also use the
trigger lines as general purpose I/O lines.
