MVS-8100L Hardware Installation 1
18 Cognex MVS-8100L Hardware Manual
Connecting External I/O Equipment
You can connect the following external I/O equipment to the MVS-8100L:
• One high-speed optically isolated trigger input that triggers image acquisitions on
one to four monochrome cameras
• One high-speed strobe output that allows MVS-8100L-controlled illumination of the
scene under one to four monochrome cameras
• One software-controlled optically isolated output that can be used by your vision
processing application as an accept/reject or status control line
Trigger and strobe lines can be connected to either the trigger and strobe expansion
panel or to certain pins on the camera port 1 connector. Status output lines can only be
connected to the trigger and strobe expansion panel.
Note Either camera port 1or the trigger and strobe expansion panel can
be used to provide trigger and strobe signals. Both sources can not
be used to provide signals at the same time
Connecting I/O Lines to the Trigger and Strobe
Expansion Panel
To connect I/O lines to the trigger and strobe expansion panel:
1. Ensure that the trigger and strobe expansion panel is installed correctly. See
Installing the MVS-8100L on page 9.
2. Make up external lines and connect them to the DB- 9F connector. See Trigger and
Strobe Expansion Panel on page 31 for schematic, signal, and pinout information
for the DB-9F connector.
Connecting I/O Lines to Camera Port 1
With the use of a special Cognex camera cable, camera port 1 can supply both camera
and trigger and strobe signals. The accept/reject I/O status line is not available through
camera port 1.
To install I/O lines to camera port 1:
1. Connect the camera splitter cable, Cognex P/N 300-0178, to camera port 1. This
cable separates the trigger and strobe lines from the camera control lines.
2. Make up external I/O lines and connect them to the RJ-12 jack of the camera splitter
cable. See Camera Splitter Cable on page 27 for pinout of the RJ-12 jack.
