22 NI Discovery Protocol

Discovery of networked National Instruments devices (targets) by other devices (hosts) requires bi-directional communication between host and target. By default, National Instruments devices do not have communication restrictions. However, devices that are not produced by National Instruments may use firewall software as a security measure to restrict communication. National Instruments network device discovery requires access to the following ports.

Port Protocol Description
5353 UDP Discovery of devices using the multicast Domain Name System (mDNS) protocol
44515 UDP Discovery of legacy devices in safe-mode when a routable IP address is not known
44516 TCP Discovery of legacy devices in safe-mode when a routable IP address is known
44525 UDP Discovery of legacy devices in run-mode
52725 TCP NI Network Browser utility
3580 UDP web monitoring and configuration server port
