Matrox Electronic Systems II - Manual (Page 50)

50 Chapter 4: Using multiple Matrox Meteor-II boards
If you are installing an additional Matrox Meteor-II board on
Matrox 4Sight, the module already installed has the setting
fixed at 0; therefore, the setting of the additional module must
be at a setting other than 0 or 4.
Grabbing simultaneously from different
boards
You can simultaneously grab images from cameras attached to
different Matrox Meteor-II boards. To grab at exactly the same
time, the cameras must be genlocked (synchronized) and their
corresponding digitizer configuration formats must be the
same. Note that this restriction does not apply to Matrox
Meteor-II /1394
The number of cameras from which you can simultaneously
grab is determined by the PCI bandwidth available in your
computer.
