Real-Time System Integration (RTSI)
Real-Time System Integration (RTSI) is a set of bused signals among
devices that allows you to do the following:
• Use a common clock (or timebase) to drive the timing engine on
multiple devices
• Share trigger signals between devices
Many National Instruments DAQ, motion, vision, and CAN devices
support RTSI.
Note RTSI is not supported on USB devices.
In a PCI system, the RTSI bus consists of the RTSI bus interface and a
ribbon cable. The bus can route timing and trigger signals between several
functions on as many as five DAQ, vision, motion, or CAN devices in the
computer.
In a PXI system, the RTSI bus consists of the RTSI bus interface and the
PXI trigger signals on the PXI backplane. This bus can route timing and
trigger signals between several functions on as many as seven DAQ devices
in the system.
RTSI Connector Pinout
Figure 9-2 shows the RTSI connector pinout and Table 9-1 describes the
RTSI signals.
