HI all,
A lot of both heat and light in these posts but I believe the real issue was cleaning up noise.
In my ignorance I must ask why the filtering doesn't take place adjacent to the parallel connector: i.e. signal condition before
you shove the outgoing signals down the line to the board set. I'm thinking here of a small board that lies between the parallel
connector and the computer end of the cable.
Of course this does nothing for the cleaness of the signals going the other way.
Maybe someone can review the pro's and con's of this one.
Tnx.
Dave
