National Instruments has announced the NI PCIe-8236 and NI PCIe-8237R two-port GigE Vision frame grabbers featuring PoE technology. The NI PCIe-8237R features NI LabVIEW FPGA-enabled I/O, including isolated digital inputs and outputs, as well as bidirectional TTL lines for implementing custom counters, PWM signals and quadrature encoder inputs.
It also offers advanced triggering and synchronisation options, such as a low-jitter, low-latency FPGA-based network trigger as well as RTSI synchronisation bus support.

Both frame grabbers are fully compliant with isolation specifications in the PoE standard to provide additional safety for the vision system and its operators. They can also interface with the latest low-cost PoE cameras on the market as well as non-PoE GigE Vision cameras with cable lengths up to 100 m.

“With these new frame grabbers, you can power a camera, perform triggering and acquire images from a single Ethernet cable,” said James Smith, Director of Industrial Embedded Marketing at National Instruments. “Engineers are constantly being challenged to do more with less, so this is a huge advantage for anyone building a vision system.”

News Highlights
• NI releases two new two-port GigE Vision frame grabbers featuring Power over Ethernet technology with the option of FPGA-enabled I/O.

• PoE technology reduces the need for additional external power supplies by powering cameras over the Ethernet bus, streamlining system design and reducing cabling complexity.

• The frame grabbers also feature advanced triggering and synchronisation options such as an FPGA-enabled network trigger for performing deterministic, low-latency camera triggering over Ethernet.
