I have purchased a parallel port breakout board over the internet. It is supposed to keep a consistant 5V signal, and will run 5 axis. The problem is, that the website has no documentation. The board has the connections printed on it, but the actual terminals have been mounted in a way that covers the printing. I was hoping that someone with experience with these cards could help me out. I think I can tell which ones are for the actual step signals, and I see that some of them are input signals, but there is a terminal block tha has two two terminals. I don't know if this is meant for the e-stop circuit, or if it is for a 5vdc supply. I don't know if the 5vdc is supplied externally or is supplied through the Parallel port. I have attached some pictures of the board. Any help would be appreciated.
