NI 17xx User Manual
To connect any additional I/O signals necessary for your application, refer to Chapter 3,
Connectors , for complete pin information.
When power is first applied to the smart camera, the POWER LED flashes red for one second
while internal systems power up. The POWER LED then lights green when power is correctly
wired to the smart camera.
Power Requirements
The smart camera uses a nominal 24 VDC power source. The smart camera accepts power within
the range of the industry standard IEC 1311 input power specification (24 V +20%/-15% with
an additional allowance for an AC peak of +5%). Refer to Appendix A,
Specifications , for
complete power requirement specifications.
Caution The 24 V external lighting strobe is an unregulated output dependent on
the range of the power supply provided to the smart camera. If the power provided to
the smart camera is +20%/-15% with +5% AC ripple, the external lighting strobe
output could be as high as 30 V. If the provided power exceeds the input voltage
specifications of the third-party lighting controller, do
not connect the 24 V lighting
strobe output to the controller to prevent damage to the controller. Use a power
supply with tolerances that meet the requirements of the controller, or use the 5 V
external lighting strobe.
If you are using the Direct Drive lighting controller, the power supply wattage must be sufficient
to power both the camera and the light. The power required by the light can be significantly more
than the power required by the smart camera. Refer to Chapter 4,
Connecting Lighting and
External Devices , for more information about using external lighting.
Connect to the Development Computer
The NI 17xx Smart Camera can connect to the development computer directly or through a
network. To configure the NI 17xx Smart Camera through a network, the NI 17xx Smart Camera
and the development computer must be connected to the same subnet.
Caution To prevent data loss and to maintain the integrity of your Ethernet
installation, do not use a cable longer than 100 m. National Instruments recommends
using a shielded twisted pair cable for maximum signal integrity.
Direct Connection
To connect the NI 17xx Smart Camera directly to the development computer, use an Ethernet
cable to connect from the Ethernet port on the development computer to Ethernet port 1 on the
smart camera. For NI 1712 Smart Cameras, use the single Ethernet port.
