A PoE (Power over Ethernet) GigE Vision frame grabber from Stemmer Imaging is set to boost the use of PoE cameras in machine vision applications. Since few PCs have direct PoE interfaces, this frame grabber provides a cost-effective way of using the space-reducing and cost-saving benefits of PoE cameras, says the company. The ADLink GIE62+ PoE frame grabber allows power and data to be send over a single Ethernet cable to a PoE camera, eliminating the need for a separate power cable and power supply for the camera. The PCI Express x4 frame grabber supports two independent GigE ports. The frame grabber can also be used with non-PoE GigE Vision cameras. The frame grabber combines the benefits of PoE technology with GigE data transmission rates up to 1000Mbit/s over cable distances up to 100m in length. The two independent GigE ports are also compatible with Link Aggregation-enabled cameras where two Ethernet ports are linked to double the data transmission rate. The frame grabber automatically detects both PoE and non-PoE devices connected to it to prevent power being sent to non-PoE cameras. It contains a power-management IC to provide short-circuit, inrush current, and current-limit protection to protect the connection between the frame grabber and PoE or non-PoE cameras. PoE cameras may be hot-plugged removing the need to restart the computer.
