NI-TSN (1588 and 802.1AS Synchronization)

At the core of every NI TSN enabled device is the 1588 or 802.1AS precision time protocol. NI-TSN devices use the precision time protocol to synchronize their internal clocks over a IEEE 1588 or 802.1AS network. This fundamental trade is taken as an advantage in many NI products.

DAQ Based Devices

How do I monitor and configure 802.1AS and 1588 Timing Protocols running on NI TSN enabled devices?

The default 1588/802.1AS configuration is suitable for many applications. However, if you wish to configure or monitor 802.1AS/1588 time references you can utilize NI-Sync API. The NI-Sync API allows local(RT targets only) and remote(Windows and RT targets) time protocol monitoring and configuration.
