From what I gather my 634 USB(ver 2.2) doesn't have the "usb board" hence making it a serial module. I noticed this from another post that referenced JPF. Anyhow I'm using a straight through serial cable and it's not powering up. I have used two different laptops here at work and plan to try another here in a few. From what I can tell it's configured for serial mode (JPA open) is there anything I'm missing? I've read the manual and I don't see anything that helps.
