Our lab uses a Lumina Response system hooked up to a Philips 3T scanner for fMRI research. Everything works fine using the trigger signal from the 3T scanner.
But for testings purposes (i.e. running the experiment in my office where I write the code), what is the cheapest way to simulate the TTL Pulse? It has to be something that can be set to a timed trigger (every 1.4s, or something like that), not a manual control only kind of thing.
Thanks

If you have another eprime based computer you can write another program to execute inline code to send a "1" out one of the bits on the parallel port. then run a cable between the two machines.
see the web support article 1320 - INFO: General Parallel Port Information
on how to write.
btw : are you using inline code to read the ttl? if so i'd love to see that.

There is a program called "ezlog" that can simulate pulses that I use as a test....I believe it can be downloaded after a quick google search or better yet ill add a .zip attachment...I hope this helps
