Connecting Parallel I/O Devices
The MVS-8600 supports the connection of I/O devices over parallel signal interface
lines, including triggers, strobes, encoders, sensors, LEDs, switches, and
programmable controllers.
Triggers, Strobes, and Encoders
Connect wires from trigger, strobe, and encoder devices to the frame grabber’s I/O
connection module, Cognex part number 800-5885-1. The I/O module extends selected
signals from the frame grabber’s Hirose HR10 connector out to screw terminals to
connect device wires. Connections of this type are described in more detail in sections
below.
Note The I/O connection module operates in three different modes,
depending on both the loaded software I/O configuration
and the
cable that you use to connect the module to the MVS-8600. The
cable part numbers and software I/O configurations are listed in
Table 3 on page 31
Programmable I/O Lines
Other devices such as sensors, LEDs, switches, and controllers can be managed and
controlled by the MVS-8600 under the direction of your vision processing application.
Connect such devices to the programmable opto-isolated input or output lines that
originate on board connectors P4 or P6. To bring the P4/P6 signals to the PC’s back
panel, connect the I/O extension cable (Cognex part number 300-0240) to P4, or P6, or
both.
Note Unlike the Hirose HR10 connector, which exposes a subset of the
I/O lines, the P4 and P6 connectors expose
all available I/O lines on
the MVS-8600.
The other end of the I/O extension cable replaces an empty slot cover on the host PC’s
back panel. As an alternative, you can remove the DB-25 connector from the cable’s
panel plate and mount it into a knock-out on the back of the PC.
