Thanks David! I have contacted Jim in the communications software dept. He was extremely helpful and we have resolved the issue.
IPP with the legacy cards (CONNECTUPS-X, etc.) doesn't require a login and password. IPP with the newer cards such as NETWORK-MS, etc. do!
So, in your IPP configuration on the computer/server, select the "Settings", "Shutdown" section, then edit the "Power Source", and in the "Access Parameters" section, enter the login and password that you configured for the NETWORK-MS card.
Communications errors fixed!
