I’m looking for the pinout of the serial port on a Carbonite Black Plus switcher. All the manuals show this as a DB9, but it’s an RJ45. Does anyone have documentation on this pinout? ---

Sorry about that. You can use the Ultra example here as they are the same. Also checked the Carbonite Solo which has the same pinout on a RJ45 as well. ---

Perfect, thank you!
