Glossary
• Auxiliary signal.
An auxiliary signal is a user-defined I/O signal that can have one or more additional
functions. For example, a signal that can be both a trigger signal and a user-defined
input signal, is an auxiliary signal.
• IP67 enclosure.
An IP67 enclosure is a specific type of industrial enclosure that is dust and
water-tight. The name is derived using the incarnation protection rating (or
ingress protection code), and defined in the international standard IEC 60529.
•Sinking.
A DC circuit that provides the common reference (low) for the circuit. In the case
of your Matrox Iris GTR, determining whether the connection is sinking or
sourcing determines how to connect the auxiliary input common signal and
auxiliary output common signal, respectively.
•Sourcing.
A DC circuit that provides the voltage needed for the circuit. In the case of your
Matrox Iris GTR, determining whether the connection is sinking or sourcing
determines how to connect the auxiliary input common signal and auxiliary
output common signal, respectively.
• Wire-terminal.
A wire-terminal is designed to receive a stripped wire; the stripped wire can carry
a signal. Typically, multiple wire-terminals are grouped together into an open-wire
connector.
