50 Chapter 3: Using multiple Matrox Indio boards
Installation of multiple boards
You can install and use multiple Matrox Indio boards in one computer.
Install each additional Matrox Indio board as you installed the first board (refer
to Chapter 2: Hardware installation). The number of Matrox Indio boards that
you can install is primarily dependent on the number of physical slots in your
computer, and your BIOS; your BIOS establishes how many PCIe devices can be
mapped to the PCIe memory space of your computer.
Using MIL-Lite, you capture images from GigE Vision cameras, connected to
different Matrox Indio boards, as you would capture images from cameras
connected to a single Matrox Indio board. That is, you allocate a single Matrox
GigE Vision system (MsysAlloc with M_SYSTEM_GIGE_VISION) and
allocate a digitizer for each camera (network camera) that you want to use to
capture images and/or access directly, using MdigAlloc().
To access the other functionality on the Matrox Indio boards using MIL-Lite, you
must allocate a MIL Matrox Indio system for each board (MsysAlloc() with
M_SYSTEM_INDIO) and then allocate the resources of each MIL system.
Simultaneous image capture from different
boards
In addition to capturing images from multiple video sources with a single Matrox
Indio board, you can also simultaneously capture images from video sources
attached to multiple Matrox Indio boards.
Note that the number of video sources from which you can simultaneously capture
images is limited by the Ethernet connection of each board. The use of a Gigabit
Ethernet (1000 BaseT) connection will optimize the speed of data transmission
from the connected cameras and will minimize data loss. In a Gigabit Ethernet
(1000 BaseT) connection, each Matrox Indio board can sustain a maximum
bandwidth of 1 Gigabits.
