National Instruments 781169-01

The National Instruments part number 781169-01 designates the PCIe-1433 Frame Grabber Device, specifically engineered for interfacing with Camera Link-compatible cameras in various configurations—Base, Medium, Full, and Extended Full. This device is equipped with two 26-pin MDR connectors, enabling high-speed data transfer and flexibility in camera connectivity. For Base configuration, a single connector can be utilized, while the Medium, Full, and Extended Full configurations allow for both connectors to maximize throughput. The PCIe-1433 supports Power over Camera Link (PoCL), which supplies power to the camera via the Frame Grabber's power cable, thereby eliminating the need for separate power supplies. The PoCL feature includes SafePower, ensuring that only PoCL-compatible cameras can draw power from the device.

This frame grabber is outfitted with advanced high-speed DMA controllers, facilitating efficient data transfer between the device and host memory, including scatter-gather DMA capabilities for continuous image transfers and storage of memory fragments. With a PCI Express interface compliant with PCIe 1.1 standards, the device is designed for x4 slots but is also functional in x8 or x16 slots in an up-plugging configuration. The PCIe-1433 accommodates up to seven RTSI bus triggers and one externally programmable trigger, allowing for customized polarity and direction.

Additionally, the 781169-01 supports region of interest (ROI) acquisitions, which enhance processing efficiency by focusing on relevant portions of the image. Operating within a temperature range of 0 to 50 degrees Celsius and a relative humidity of 10% to 90% (non-condensing), the device is intended for indoor applications and remains functional at altitudes up to 2,000 meters. The frame grabber adheres to international safety and EMC standards, ensuring dependable performance across various environments. Compact and lightweight, the device measures 10.7 cm by 17.5 cm (4.2 in. by 6.9 in.) and weighs 205 grams (7.23 oz), facilitating ease of installation and portability.
