Power source connector
The power source connector is a combination of one DC power socket and two
wire terminals. You can use either the DC power socket or the two wire terminals
to connect the power supply to the Matrox breakout board. Note that a DC power
supply is provided in the Matrox Iris GT starter kit. Alternatively, you can connect
an open-wire power supply to the J19 and J20 wire terminals.
❖ Note that the wire terminals are meant to receive power from an external source
and should not be connected to the open-ended digitial I/O and power cable.
The pinout for the power source connector is as follows:
