If you decide to build a custom cable, National Instruments recommends
that you use twisted pair wiring to help reduce noise pickup from outside
sources and crosstalk. TTL I/O lines should be twisted together with a wire
connected to DGND. Isolated input and RS-422 input lines should be
twisted together in their proper +/– pairs.
Refer to the Connectors
connector pin assignments.
Use a 3M Camera Link cable to connect your camera to the MDR 26-pin
connector on the IMAQ 1426 device. Camera Link cables consist of
two MDR 26-pin male plugs linked with a twin-axial shielded cable and
are available in two shell configurations.
Refer to the Specifications of the Camera Link Interface Standard for
Digital Cameras and Frame Grabbers manual for more information about
Camera Link cables.
