Hello,

I do a lot of work with parallel port communication between computers or from a computer to "dumb" devices accepting triggers. I'm looking for a device/tester that I can plug into the parallel port which will light an LED or indicator of some sort when a specific pin or multiple pins are set to high. From looking around on the internets I'm seeing a lot of BIOS stuff as far as parallel port testers but nothing like a simple LED circuit. Some help with this would be GREATLY appreciated.

Thanks!

Sorry for the confusion, I meant set high as in +5v. Not looking for a baud tester, as that's all I am seeing when looking for "parallel port tester". Need something that will light an LED connected to a pin when that pin is triggered.

So if someone wrote a command that triggered the "2" pin on the parallel port, I'm looking for a device that will light an LED which corresponds to "2" (or something like that) on the board.

Ah! Thank you so much for the link. It wasn't working before I responded but that's exactly what I'm looking for!

Any chance you know where to find something like the one at the link - except a bit "prettier". I'm looking to deploy a few of these around my office and something a little more put-together would be nice.

Not that I know of, you could always mount it inside of a plastic "Project Box" if you were so inclined.

Hey Ryan, did you make any progress in finding your ready-made parallel-port LED tester? I'm looking for the exact same thing and don't want to build one myself.

Cheers,

Stef
