4.
Unscrew the ground screw on the back panel of the CDC camera for one rotation,
leaving the screw attached to the camera. Wrap the end of cable 300-0062’s shield
ground wire around the screw and retighten it.
5.
Attach cable 300-0362’s 4-pin female Molex connector to the male Molex connector
on the back of the CDC series camera. The Molex connector on the cable snaps
into place and locks to the camera.
6.
The other end of cable 300-0362 terminates in four wires with tinned ends, in two
twisted pairs, labeled /– and T/–.
7.
Connect the T/– wires to the positive and negative terminals of your trigger
device, respectively.
If your trigger device terminates in bare wires, then twist the camera’s wire
to the trigger device’s plus wire, then cover the joined wires with a wire nut or
another insulator. Join the camera’s Trigger– wire to the device’s minus wire in the
same way.
8.
Connect the /– wires to the positive and negative terminals or wires of your
strobe device, respectively.
See
Hardware Trigger and Strobe Connections
on page 54 for more on the
requirements of your trigger and strobe devices, and for diagrams of the opto-isolated
circuitry of the camera’s trigger and strobe connector.
Connecting Parallel I/O Devices
The MVS-8100D supports the connection of general use I/O devices such as status
LEDs, part reject switches, and so on. The MVS-8100D provides 8 or 12 parallel I/O lines
that can be controlled by Cognex software. You can use the MVS-8100D’s I/O lines as
TTL lines, or, when used with the Cognex external I/O module, as opto-isolated lines.
Table 3 shows the available I/O lines for the two connection options by model.
