Exporting Timing Output Signals Using PFI Terminals
You can route any of the following timing signals to any PFI terminal
configured as an output.
• AI Convert Clock*
• AI Hold Complete Event
• AI Reference Trigger
• AI Sample Clock
• AI Start Trigger
• AO Sample Clock*
•AO Start Trigger
• Counter n Source
• Counter n Gate
• Counter n Internal Output
•Frequency Output
•PXI_STAR
•RTSI<0..7>
• Analog Comparison Event
• Change Detection Event
• DI Sample Clock*
• DO Sample Clock*
Note Signals with a * are inverted before being driven to a terminal; that is, these signals
are active low.
Using PFI Terminals as Static Digital I/Os
Each PFI can be individually configured as a static digital input or a static
digital output. When a terminal is used as a static digital input or output,
it is called P1.x or P2.x. On the I/O connector, each terminal is labeled
PFI x/P1.x or PFI x/P2.x.
In addition, M Series devices have up to 32 lines of bidirectional DIO
signals.
