I/O Connector
The I/O connector is a 17-pin male M12 connector that provides power to
the camera and transmits digital I/O signals.
Figure 3-2.
I/O Connector
The I/O connector includes 4 open collector output connections, including
2 output connections which can be used as strobe signals. An open collector
output is not capable of providing voltage to a connected device. Instead,
power is provided by the connected device and is either grounded or not
grounded by the open collector connection. Each connection is protected
by a 100 mA fuse. The I/O connector also includes a controlled current
output capable of providing current to a LED light.
The I/O connector includes 4 independent opto-coupled input connections,
which share a common ground connection with the NI 177x Smart Camera.
Each input can be configured to generate interrupts and reject signals that
are shorter than a specified width. The I/O connector also includes an
optically isolated trigger input.
