The NI 9469 is a cabled timing and synchronization C Series module used to route clocks and triggers between multiple chassis. The NI-DAQmx and NI-RIO drivers are shipped with default master/slave configurations for quick synchronization applications, but you can also customize the routing of the trigger and clock lines between the inports, outports, and chassis to create large-scale systems with custom timing and triggering. See the "Routing" section of the user manual for more information on possible route combinations.

Analog Input Synchronization With CompactRIO
The NI 9469 was designed to synchronize modules with simultaneous delta-sigma analog-to-digital converters for high-channel-count systems that require more than one chassis. Delta-sigma modules require a separate oversample clock to operate. Each delta-sigma module has an onboard clock for normal operation that is physically routed through the CompactRIO chassis to synchronize all delta-sigma modules within a single chassis. For multichassis systems, the NI 9469 generates the required oversample clock for delta-sigma modules and routes it to both the local CompactRIO chassis and any other CompactRIO chassis connected by an NI 9469. Delta-sigma modules include the NI 9225, NI 9227, NI 9229, NI 9232, NI 9233, NI 9234, NI 9235, NI 9236, NI 9237, NI 9239, NI 9242, and NI 9244.

In addition to delta-sigma synchronization, you can program the four input lines and eight output lines (four per port) of the NI 9469 for custom trigger schemes. The timing characteristics of this functionality are similar to any other CompactRIO digital module.

Chassis Synchronization With CompactDAQ
The NI 9469 can synchronize all module types across multiple CompactDAQ chassis, including analog input (AI) tasks with any AI module type, analog output tasks, and digital I/O and counter tasks. An NI-DAQmx task runs I/O channels from a single clock source. With an NI 9469 installed in each chassis, multiple chassis can share task timing for a distributed, synchronous DAQ system.
