I'm trying to interface a simple hydrodynamic bar feeder (SMW Omnibar) to a Haas MiniLathe. All I need are an end of bar signal to be given to the lathe and an e-stop to come from the bar feeder. The e-stop is no problem. I'm having trouble with the end of bar, though. The book says to use discrete input A161 on the IOPCB. It says that this is located in connector P52, but I don't have a connector P52 on my IOPCB. It's labeled on the board, but there's nothing soldered at that spot. I'm thinking that the book is wrong about the location of this discrete input because it was wrong about the location of the e-stop circuit. It said it was at P40, but I actually found it located at P6. Does anyone know the correct location on the IOPCB of this discrete input? Or any other spare discrete inputs that I could use? The book also says to see the "Technical Reference" section for a description of the 1-bit discrete inputs, but I can't find that section. I'm beginning to dislike this Haas book... It's actually an SL series book, but it's what came with the machine. And I tried calling Haas yesterday but gave up after sitting on hold for 45 minutes. I'm really hoping someone out there has the info I need. Thanks!
