Reading Digital Pulse with PCIe 6509

Hello everyone,

I'm trying to decode an Infrared signal from a remote control using the PCIe 6509, but I'm having no luck doing that. It seems that when I'm using the Change Detection VI it does generate the interrupt, but it can't produce it fast enough to create a pattern to use with the Daqmx Read VI. Does anyone know if something like this is possible? The idea is to make the PCIe 6509 generate a digital output signal for each differente key on the controller.

Thanks!

Kenny
