A can send and receive signals through the front panel connectors and the trigger bus. The front panel connectors provide connectivity for the input and output signals and for the control lines that send and receive clocks, triggers, and events. You can use the trigger bus to send and receive events, triggers, and Sample and Reference Clocks.

Signals can be routed to and from the supported front panel connectors of your device. All signal routing operations can be characterized by a source and a destination. The possible signal routes for your device depend on the device, the chassis, and the occupied chassis slot. Refer to your chassis documentation to determine the configuration of trigger bus segments of your chassis.

Note trigger bus lines are shared globally across devices in a chassis. The availability of trigger bus lines may be affected by other applications that share the chassis you are currently configuring.

Static and Dynamic Routes

When a signal is exported to a trigger line from a device, only devices in the same chassis segment recognize the signal from that trigger line. To route the signal to devices in a different chassis segment, you must establish a static or dynamic route.

A dynamic route is a type of signal route that is specified by only the route endpoints. The actual route is determined automatically in software and is reserved and unreserved based on the NI-RFSA session using that route. To release a dynamic route, close the NI-RFSA session(s) using that route.

A static route is a type of signal route that you must create manually. To create and configure static routes, you must use the NI-DAQmx API.
