Cabling
This appendix contains cabling requirements for the IMAQ PCI-1426
device, including Camera Link cable ordering information.
15-Pin D-SUB Cable Specifications
National Instruments provides a generic 15-pin cable assembly kit
(part number 190912-04) that breaks the connector out into 15 color-coded
wires for easy connectivity. Visit the National Instruments Web site at
ni.com/catalog
to purchase a cable assembly kit for the IMAQ 1426.
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 /– pairs.
Refer to the
, for
connector pin assignments.
Camera Link Cables
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.
Note
National Instruments recommends purchasing a Camera Link cable. Building your
own cable is not recommended due to the high-speed signaling on the Camera Link
interface.
Refer to the
Specifications of the Camera Link Interface Standard for
Digital Cameras and Frame Grabbers
manual for more information about
Camera Link cables.
