Connecting Matrox Meteor-II /Multi-Channel to other

boards

The VMChannel interface allows the transfer of data to other
Matrox boards. Insert a VMChannel backplane (available wi th
interconnect kits) across the VMChannel interface to connect
the boards. Note that when connecting multiple Matr ox boards,
at least one of the boards you are connecting must be
bus-controller capable. Matrox Meteor-II is not bus-controller
capable.

Connecting Matrox Meteor-II /Multi-Channel to the

auxiliary power supply input

To use Matrox Meteor-II /Multi-Channel to power your camera:
1. Use the 4-pin power cable to connect the auxiliary power
supply connector to the power supply in the computer.
2. Ensure that the jumper is across the appropriate Matrox
Meteor-II auxiliary power supply selection pins, for the
required voltage (5 V or 12 V). See Appendix B for a
diagram.
3. Use the DBHD44-TO-8BNC/O cable to connect your
camera’s video output and power supply input to the video
input connector. Note that the total current d rawn by all
the cameras is limited to 1.5A, and the circuit uses an
auto-resettable fuse.
