counter trigger

Hi All,

i use ni-6111 (Nidaqmx; C++, Delphi,VB), start the measurment for one channel ai0 over a trigger signal from counter0, it works; but want to start counter1 with same trigger signal, which fails.

if i try to generate event when counter0 changes gets error too, suppose not supported event for 6111? found no document for this.

Is there a way to use one counter as trigger source for the other counter and one ai channel?

Thanks,

hassan
