© National Instruments | 1-5NI 17xx User ManualTo 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 secondwhile internal systems power up. The POWER LED then lights green when power is correctlywired to the smart camera.Power RequirementsThe smart camera uses a nominal 24 VDC power source. The smart camera accepts power withinthe range of the industry standard IEC 1311 input power specification (24 V +20%/-15% withan additional allowance for an AC peak of +5%). Refer to Appendix A, Specifications, forcomplete power requirement specifications.Caution The 24 V external lighting strobe is an unregulated output dependent onthe range of the power supply provided to the smart camera. If the power provided tothe smart camera is +20%/-15% with +5% AC ripple, the external lighting strobeoutput could be as high as 30 V. If the provided power exceeds the input voltagespecifications of the third-party lighting controller, do not connect the 24 V lightingstrobe output to the controller to prevent damage to the controller. Use a powersupply with tolerances that meet the requirements of the controller, or use the 5 Vexternal lighting strobe.If you are using the Direct Drive lighting controller, the power supply wattage must be sufficientto power both the camera and the light. The power required by the light can be significantly morethan the power required by the smart camera. Refer to Chapter 4, Connecting Lighting andExternal Devices, for more information about using external lighting.Connect to the Development ComputerThe NI 17xx Smart Camera can connect to the development computer directly or through anetwork. To configure the NI 17xx Smart Camera through a network, the NI 17xx Smart Cameraand the development computer must be connected to the same subnet.Caution To prevent data loss and to maintain the integrity of your Ethernetinstallation, do not use a cable longer than 100 m. National Instruments recommendsusing a shielded twisted pair cable for maximum signal integrity.Direct ConnectionTo connect the NI 17xx Smart Camera directly to the development computer, use an Ethernetcable to connect from the Ethernet port on the development computer to Ethernet port 1 on thesmart camera. For NI 1712 Smart Cameras, use the single Ethernet port.
