138 Appendix F: The breakout board
• When connecting to an inductive load device, use an external diode between the
+VDC and your third-party device.
For more information about connecting inductive load devices, refer to Connecting
to an inductive load device subsection of the Connecting external devices to auxiliary
output signals section, in Appendix D: Using the I/O signals and controlled- current
output of Matrox Iris GT.
❖ Note that when routing output signals from the smart camera connector, the
observed voltage at the output pin will be low when auxiliary output signals are
set to on and high when auxiliary output signals are set to off if there is an external
pull-up resistor connected. Without an external pull-up resistor connected, the
observed voltage at the output pin will be floating when auxiliary output signals
are set to off. For more information, see Connecting external devices to auxiliary
output signals section, in Appendix D: Using the I/O signals and controlled- current
output of Matrox Iris GT.
