The user manual shows a straight through cable to upload an application from a PV550. It's talking to a SLC500, on DH485, 19.2 K, etc. I hook up my straight cable right to the PV RS232 port (the only port), and do an auto-config...nothing. Am I using the right cable? Looking for any input. I just want to make a few screen changes and download it again. Do I have to stop the application to see it in RSLinx?
Thanks
