Grabbing Simultaneously From Different Boards - Matrox Meteor-II Installation And Hardware Reference Manual

PCI bandwidth
requirements
In addition, you should 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
setting for the dedicated signals.
Switch position Board position
0 or 4 1
1 or 5 2
2 or 6 3
3 or 7 4
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; however, the number of cameras from which you can
simultaneously grab is determined by the PCI bandwidth available in your
computer.
Matrox Meteor-II /Multi-Channel has a low susceptibility to PCI bus latency due
to its 4 Mbytes of video transfer memory. In addition, sustained PCI-transfers to
memory require the use of a high performance PCI core-logic chipset, such as the
Intel 820, 840, 850, 860, or E7505. If a high performance chipset is used with a
Matrox Meteor-II /Multi-Channel board, you should not have any PCI
