Multiple Digital Triggers Using RTSI between MIO Board and DIO Board
Print
This VI illustrates how to use the DIO 32HS in change detection mode to expand the triggering capability of an MIO board.
MIO boards capable of digital triggering can start an acquisition when a digital signal arrives on one particular pin; therefore, you are limited to only one trigger line per board. If you have a DAQ application that can potentially be triggered by more than one source, you can OR the signals with your own circuits or, instead, use the DIO 32HS in change detection mode. When a line changes state, the 32HS asserts the REQ. Then, as shown in this example, the signal routes to RTSI, and to the digital trigger line of the MIO board.
