DAQ-Sync signals

The DAQ-Sync hardware provides the capability of triggering or clocking up to four slave boards from a master
board to synchronize data input and/or output.
The PCI-DAS6034, PCI-DAS6035, and PCI-DAS6036 boards provide the capability of inter-board
synchronization between boards in the PCI-DAS6000 family. There are five trigger/strobes and a synchronizing
clock provided on a 14-pin header. The available signals are:
DS A/D START TRIGGER
DS A/D STOP TRIGGER
DS A/D CONVERT
DS D/A UPDATE (PCI-DAS6035 and PCI-DAS6036 only)
DS D/A START TRIGGER (PCI-DAS6035 and PCI-DAS6036 only)
