Cognex MVS-8100D and CDC Cameras Hardware Manual
Hardware Triggers and Strobes
The MVS-8100D’s default setting is to expect software triggered image acquisition.
Using Cognex software, you can specify hardware triggered acquisitions and/or the
simultaneous firing of a strobe device for illumination.
If you use hardware triggering and strobing, connect wiring from trigger and strobe
devices directly to each Cognex CDC series camera, not to the MVS-8100D. The trigger
initiates an image acquisition and fires the strobe, all without the participation of the
MVS-8100D. The MVS-8100D then receives and processes the acquired image from the
camera.
The connection of triggers and strobes to the camera is discussed in
on page 14 and in
Hardware Trigger and Strobe Connections
Parallel I/O Connector
The MVS-8100D supports the connection of parallel I/O devices. The devices you
connect depend on your vision processing application, and can include, for example,
status-reporting LEDs or parts reject switches.
The MVS-8100D provides eight or twelve bidirectional TTL parallel I/O lines. Model
MVS-8100D1 supports eight lines; models MVS-8100D2 and MVS-8100D3 each support
twelve lines. When used with the Cognex external I/O module, the MVS-8100D’s
bidirectional TTL lines are converted to opto-isolated input and output lines.
When connecting TTL devices, use Cognex cable 300-0358, which connects to the
MVS-8100D’s parallel I/O port and terminates in a block of screw terminal connectors.
You can connect either incoming or outgoing devices to any I/O line on the MVS-8100D.
Cognex software is used to specify whether each TTL line is to be used as an input or
output line. The direction of each I/O line can be set independently of other lines. Cable
300-0358 and the connection of TTL devices is discussed in
