Installing the MVS-8100M
Cognex MVS-8100M Hardware Manual

Note
If you later change or add cameras or light modules after initial
installation, with the board still configured for internal camera power,
you may exceed the power limitations. For this reason, Cognex
strongly recommends using J3 in the 2-3 position and using cable
300-0175, even when connecting a single camera to your 8100.
Figure 3 shows the J3 jumper position for external 12 V power. The total available
power with the jumper in the 2-3 position is 750 ma for
each
installed camera and
3.5 A total for all cameras and light modules.

Caution
Failure to correctly attach and configure the external power cable to
your MVS-8100 as described in these steps may result in damage to
your frame grabber, motherboard, or both.
5.
Press the card into its slot until it is seated firmly, and replace the slot cover screw.
6.
Locate the 8100’s ex12 V power connector at J2, as shown in Figure 3 on
page 13. Connect the +12 V power cable adapter (P/N 300-0175) to your PC’s
power supply and to the connector at J2. Both connectors are keyed, and can only
be inserted one way.
Caution
Before you attach cameras, be sure the PC’s power is OFF.
Attaching live equipment to the 8100 can result in electrical damage.
