julito Posted February 15, 2008 Report Share Posted February 15, 2008 Hi, I'm using PCI9111 HR whit labview (DAQ LviewPNP). I have created a software to acquiere voltage variations and present acoustic stimulus (using a TDT sound generator), but I want to trigger the acquisition process whit the sound generation. I have been trying to use the circuit that I'm attaching to detect the trigger signal (generated in the TDT ge sound generator) but the program return me an error saying that the specified group is in use . I want to know if someone here have an idea about the solution of this problem. The circuit that I want to trigger is attached to this post. Regards Julio Quote Link to comment
