Adding to GigE

This Tech Tip is designed to explain some of the additions in the GigE Vision marketplace that have added to the capabilities of GigE Vision cameras.

Gig E Vision The main features of GigE Vision have been covered previously, but as a quick recap some of the points of note are:

  • Long cable lengths – upto 90m between links with the capability to use fibre - optics to go much further between links , all this with standard consumer components.

  • Network topologies – one camera to one PC , many came ras to one PC and one camera to many PCs – ethernet - based transmissio ns has opened possiblities that were not feasible with framegrabber - based systems and gone much further than was possible with USB and Firewire - based systems.

Self- describing cameras – Genicam means that a device must describe itself to a connecting PC by means of an xml file. This replaces the need for conf iguration or camera files, for example for describing the format that data streams fr o m a camera. Power over Ethernet PoE (Power over Ethernet) is a standard consumer technology that allows upto 15.4W of DC power without sacrificing the cable - length capabilities of GigE . PoE - enabled G igE camera include IDS uEye CP cameras and optionally Stemmer Imaging ’ s CVC GE cameras and the AVT Mant a and GT ranges . The advantage is that with a PoE - enabled NIC it is only ne cessary to run a single cable to the camera.
