Integration and System Considerations
RTSI Bus


RTSI stands for Real-Time System Integration. It is a bus found on many National Instruments devices that, when cabled together with a RTSI cable, is used to share and exchange timing and control signals between multiple boards. It is usually used for synchronization purposes.

The previous figure shows an example of an extended five-board cable setup.

The RTSI bus cables are short, 34-conductor ribbon cables equipped with two to five connectors to link together a group of boards. The cable options include connections for two, three, four, and five boards, plus an extended cable length to connect up to five long and short boards.
