View Full Version : How to update Rotel receiver firmware using RS232 on Mac

Mar 24, 2010, 06:09 AM
I've got a Rotel RSX-1550 receiver and there a number of new firmware updates I'd like to load myself. The problem is that Rotel update software requires a Windows computer with a RS232 DB9 port.

Has anyone with a Rotel system updated using Windows on VMWare/Parallels and a USB to RS232 serial adapter?
