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 with interconnect kits) across the VMChannel interface to connect the boards. Note that when connecting multiple Matrox 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
