Hello All,
I'm trying to find a device I can use on my parallel port to display the status of each pin each by means of LED. I'm using the parallel to control something and I need something I can plug in series with the cable.
It will help diagnosing problems.
Black Box & Tigerdirect says they use to have products as such, but no more.
I'm lazy and don't feel like building anything. If you have a suggestion please send it my way.
Or even a schematic on building something using transistors & LEDS.
I may have to build something.....if I can't find anything!
Thanks in advance,
M
