RTSI ConnectorThe PXI-7350 uses the PXI chassis backplane to connect to other
RTSI-capable devices.
The PCI-7350 uses a ribbon cable to connect to other RTSI-capable
PCI devices.
RTSI Signal Considerations
The NI 7350 controller allows you to use up to eight RTSI trigger lines as
sources for trigger inputs, or as destinations for breakpoint (position
compare) outputs and encoder signals. The RTSI trigger lines also can
serve as a generic digital I/O port. The RTSI star trigger line, which is
available only on the PXI-7350, can be used only for a trigger input.
Breakpoint (position compare) outputs are output-only signals that
generate an active high pulse of 200 ns duration across RTSI.
Encoder and Index signals are output-only signals across RTSI that are
the digitally-filtered versions of the raw signals coming into the controller.
Ify ou are using the RTSI bus for motion I/O or generic digital I/O,
alls ignals are passed through unaltered.
