Figure 4-10. Synchronizing Conversions on Multiple Boards
You can use a hardware external clock source to synchronize conversions
on multiple DAS-800 Series boards. In addition, you can use the output of
the OUT1 pin (pin 5) on a DAS-801 or DAS-802 board (acting as a
timing master) to synchronize conversions on additional DAS-800 Series
boards.
Figure 4-10 illustrates how you can synchronize conversions on multiple
boards, using both an external clock source and a DAS-802 board. Note
that in both cases, boards 1, 2, and 3 must be configured to use an
external clock.
