Hi
I have already done the I/O Test using MediaLab, and it works fine. However, I dont get a TTL signal, when I try to run a MediaLab experiment.:


Essentially, I changed the parameter field of the selfesteem.que file in Sample1, as follows:

For the parameter field of the first row, which is instructions, I have added :
(<255:888:50>)
This is because I am sending a 1 on all datapins of the parallel port. However, nothing happens.

Again, in the parameter field of the second row, I have added the following:
(<0:888:50>) . However, even this goes undetected.

I am using a relay at the other end, to detect the parallel port output.

Pls help me with it because I am stuck up here.

Thanks,
Jatan
