Matrox Indio overview
Matrox Indio is a versatile, Industrial I/O and communication, PCIe board. It
permits communication with external devices using 16 optically-isolated, digital
auxiliary I/O signals (8 inputs and 8 outputs). In addition, it has a Gigabit Ethernet
interface that supports industrial Ethernet communication and GigE Vision
capture; the Gigabit Ethernet interface has fully isolated, power-over-Ethernet
(PoE) support to power a connected device.
The following diagram illustrates the data flow of the Matrox Indio board.
