Firewall Configuration

Communication with devices is usually established from the NxLib and allowed automatically by personal firewalls. If you have a more complicated network setup you might have to allow the some traffic depending on the specific type of camera.

GigE Vision

GigE Vision based cameras (including B- and C-series) use the standardized GigE Vision protocol.

  • Discovery and network configuration:

    • UDP broadcasts to device port 3956

    • Zeroconf/DNS-SD queries for the service _gvcp._udp.local, which use Multicast DNS (mDNS) broadcasts to multicast IP 224.0.0.251 and port 5353

  • Communication: UDP with device port 3956 and device-specific additional ports for further control channels and image transmission

X-Series Projector

The X-series projector uses a different protocol than it’s sensors, which are based on GigE Vision or uEye.

  • Discovery and network configuration: UDP broadcasts to device port 24100

  • Communication: TCP with device port 24100

XR-Series Devices

  • Discovery and network configuration: UDP broadcasts to device port 24000

  • Communication: TCP with device port 24000
