synchronized timebases on your IEEE 802.1AS subnet. This enables measurement signals to
be synchronized to other devices across a distributed network.
The FieldDAQ devices use the IEEE 802.1AS protocol over the network to synchronize. They
can be configured to use the IEEE 1588 "Delay Request-Response Default PTP" profile
instead. These devices cannot synchronize with other 1588 profiles.

Ethernet Ports and Networking
The Ethernet Network Interface transfers data between the FieldDAQ device and the network.
It gathers the data into TCP/IP packets that can be sent across the network and interpreted by
the host.
Note
Setting up the FieldDAQ Device
for information about connecting the FieldDAQ device to a host
computer or host real-time controller.
Ethernet Ports
The FieldDAQ device has two 8-pin X-coded M12 Ethernet ports—0 and 1. You can use a
shielded straight-through Ethernet or an Ethernet crossover cable with either of the Ethernet
ports to network your device to a computer host, NI Linux Real-Time controller, another
FieldDAQ device, or any network connection on the same subnet. Refer to
for more information about using these ports in various topologies.
