Power-over-Ethernet frame grabbers simplify vision systems

29 April 2013

National Instruments has introduced the NI PCIe-8236 and NI PCIe-8237R two-port GigE Vision frame grabbers that feature Power-over-Etherent (PoE) technology which reduces the need for additional external power supplies by powering cameras over the Ethernet bus.

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 and 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 PoE cameras as well as non-PoE GigE Vision cameras with cable lengths up to 100m.
