I'm attempting to flash all my 193-ECM-ETR E300's to the latest version. I have mostly first gen. series A Rev 5's. I have a few Rev 6's in spares but am starting to get Series B Rev 7's in as replacements. I'm wanting to flash all my units to the latest Rev, but I'm having a hard time with control flash. The 193-ECM-ETR is not showing up in my catalog to flash. I've downloaded everything I can find on rockwells support site but nothing is helping. I need a step by step I guess. Any experience with this?? Help
