NI PCIe-1427 User Manual
A
Cabling
This appendix contains cabling requirements for the NI 1427, 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 NI 1427.
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
section of Chapter 3,
Signal Connections
, for
connector pin assignments.
Camera Link Cables
Use a standard Camera Link cable to connect your camera to the MDR
26-pin connector on the NI 1427 device. Camera Link cables consist of
two MDR-26 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. This manual is available on several Web sites,
including the Automated Imaging Association Web site at
