128 Appendix F: The Matrox Iris GTR breakout board
The pinout for the input connector (J5) is as follows:
Output connector
The output connector (J6) is a series of 5 wire-terminals. Four of these
wire-terminals (labeled OUT0 through OUT2, and OUT_COM) connect to
your third-party devices so that the devices can receive auxiliary output signals
from your Matrox Iris GTR, via an open-wire cable. The fifth wire-terminal can
output voltage to third-party devices.
If an auxiliary output signal is used as a sourcing output (that is, when the
OUT_COM wire-terminal is connected to a sinking input of a third-party device
while one of the OUT wire-terminals is connected to a voltage source), then only
1 auxiliary output signal is available.

This wire-terminal can be connected either to a voltage return path or a voltage source, depending on whether the connected
third-party device is sourcing or sinking the current, respectively. Note that, since this wire-terminal is shared among the
four auxiliary input signals, if one of the third-party devices, connected to the input connector, is sinking the current, then
they all should be.
If the IN_COM_TERM selector switch (SW6[4]) is set to ON, this wire-terminal should remain disconnected since your
Matrox Iris GTR breakout board provides the common return path or voltage signal for the auxiliary input signals of your
smart camera (depending on the setting of the IN_COM selector switch (SW2)).
To provide a voltage source less than 24 V for sourcing auxiliary input signals, connect this wire terminal to an external
voltage source and set the IN_COM_TERM selector switch (SW6[4]) to OFF.
