Timing Signal Routing
The DAQ-STC provides a very flexible interface for connecting timing
signals to other boards or external circuitry. The 611X E board uses the
RTSI bus to interconnect timing signals between boards, and the
Programmable Function Input (PFI) pins on the I/O connector to
connect the board to external circuitry. These connections are designed
to enable the 611X E board to both control and be controlled by other
boards 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 3-11.
