I want to trigger a single pulse on a PCI 6602 from the same trigger that
starts an for a data acquisition on a PCI 6071 E (PFI0 on the 6071)
Here�s part of my code which is not working. PF0 receives the pulse and
starts the DAQ, but the gate on counter 0 on the 6602 never gets a trigger.
I have a RTSI cable installed between both cards. According to the RTSI
cable manual no software has to be installed. Do I need to use RTSI_Conn
();?
BTW, iTimerBoard is the 6602 and iDAQBoard is the 6071.
