EuroDriver thanks for the info. I know Eric worked out the programming issues with the ALC when I first set up the Archon. Is the RJ cable just a standard phone cable? I was thinking about getting the IOE module but didn't think I would have a need for it. I don't have DC pumps and from what I can see from the current DC offerings the controls are built into the pumps rather than on the standard controllers that come with them. I do use an APC module with a DCI to control my Jebao's. I have had the controllers for these pumps die early but the APC seems to keep going and going.
