Grabbing simultaneously from different boards
31
In addition, you must set the rotary switch of each PC/104
-Plus
board to a unique
setting in the stack. Setting the rotary switch dedicates a group of PCI signals to
the board in the stack: clock, request grant, ID select, and interrupt signals. It is
recommended that the first board installed (the board closest to the Host CPU
board) be configured to 0, the second 1, and so on. The table below shows the
recommended switch setting for each board, as well as the corresponding settings
for the dedicated signals.
If you are installing an additional Matrox Meteor-II board on a Matrox 4Sight-II
unit, the board already installed has the setting fixed at 0; therefore, the setting
for the additional board must be something 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.
The number of cameras from which you can simultaneously grab is determined
by the PCI bandwidth available in your computer.
