Caution
The 16-pin terminal block at the end of cable 300-0358 resembles
the terminal blocks at the end of other Cognex parallel I/O cables for
other products. However, the signal name and pin numbering on
cable 300-0358 is unique to the MVS-8100D series. Do not connect
a terminal block that works on another Cognex product into the
terminal end of cable 300-0358, or electrical damage may result.
Connecting Opto-Isolated Devices
Figure 5 illustrates the connection of parallel I/O devices to an MVS-8100D using the
opto-isolated option.
Figure 5.
Opto-isolated connection option
For the opto-isolated connection option, use cable 300-0359 to connect your
MVS-8100D to the Cognex external I/O module, P/N 800-5712-3. The external I/O
module takes the TTL signals from the MVS-8100D and passes them through optical
isolation circuitry, splitting each TTL bidirectional line into a plus and minus pair of either
input or output lines. You then connect parallel I/O devices to screw terminals on the
external I/O module.
The Cognex external I/O module is described in more detail in
To connect opto-isolated parallel I/O devices to the MVS-8100D, follow these steps:
1.
Connect Cognex cable 300-0359 to the HD-15M port on the faceplate of the
MVS-8100D.
Caution
The MVS-8100D’s parallel I/O port resembles the industry standard
VGA connector, but is wired differently. Do not connect a monitor to
this port, or you may damage your MVS-8100D, your monitor, or
both.
2.
Connect the other end of cable 300-0359 to the HD-26F port labeled “Vision
Processor” on the Cognex external I/O module.
