Timing Signal Routing

National Instruments Corporation
The DAQ-STC provides a very flexible interface for connecting timing
signals to other modules or external circuitry. Your VXI-MIO Series
module uses the VXIbus trigger for interconnecting timing signals
between modules and the Programmable Function Input (PFI) pins on
the I/O connector for connecting to external circuitry. These
connections are designed to enable the VXI-MIO Series module to both
control and be controlled by other modules and circuits.
There are a total of 13 timing signals internal to the DAQ-STC that can
be controlled by an external source. These timing signals can also be
controlled by signals generated internally to the DAQ-STC, and these
selections are fully software-configurable. For example, the signal
routing multiplexer for controlling the CONVERT* signal is shown in
Figure 3-9.
