MDR 26-Pin Connector
Each MDR 26-pin connector provides reliable high-frequency transfer
rates between a camera and the image acquisition device. To access these
connectors, use one MDR 26-pin Camera Link cable per Base
configuration camera. Refer to the
section for additional
information about Camera Link cables, including ordering information and
cable lengths.
SMB Connector
The SMB connector can be used for front panel trigger connectivity. It can
be used as a 5V input to trigger acquisitions or as a 5V output to provide
status information to your system. For further triggering and DIO needs,
use the NI Camera Link I/O Extension Board. The I/O Extension Board
provides three differential isolated inputs, three isolated outputs, eight TTL
inputs/outputs, and quadrature encoder inputs.
Cabling
Use a standard Camera Link cable to connect your camera to the MDR
26-pin connector on the NI 1430 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
