I need a hardware solution - preferably off the shelf. I used something like this 15 years ago and have no idea if anyone still makes them - any ideas?
**** I need to be able to generate a TTL signal when the "Enter" or <CR> key is pressed on a PC keyboard. I used a box to do this (a long time ago) which plugged into the keyboard cable (old IBM, non-usb DIN type) between the keyboard and the PC and was powered by the PC. The box generated a TTL signal when any key was pressed. **** The background to this is that I have to start a data collection by two standalone PC's at the same time - one of the applications is completely self-contained with no analog control facilities at all, but the other application can be started via a TTL signal. I know keyboard interface boxes that do this sort of thing existed once (back before the world went gui on me) and I could probably build one from scratch if the customer wanted to pay and I had the time. And I realize the "at the same time" has a significant error attached to it no matter how it's done - I just want to eliminate the user error. Regards, Edmund Cramp -- I hate leaving my house confident and looking good and then not seeing anyone of importance the entire day. What a waste. _______________________________________________ General mailing list [email protected] http://mail.brlug.net/mailman/listinfo/general_brlug.net
