Open-wire connectors reference 127
Input connector
The input connector (J5) is a series of 5 wire-terminals. Four of these
wire-terminals (labeled IN3 (CAM TRIG) through IN6) connect to your
third-party devices so that the devices can send signals to the auxiliary input signals
of your Matrox Iris GTR (such as, trigger signals). The fifth-wire terminal can
connect to an external voltage source/return path for the auxiliary input signals.
Each auxiliary input signal should have only one input source. For example, when
an input signal comes from a connected third-party device, it should always be
the only source of input for that signal, and not have to compete with the signal
from a re-routed auxiliary output signal or a push button.
