I am now having problems. I got the usb to serial and the correct programming cable but the remote just won't connect to the RM820 Editor. On the MX 850 Editor I can only get it to say "Fail! 1" on the remote where the page number is.

I cannot update the software because the mx850 editor doesn't have that option and the RM820Editor says its already up to date.

I always make sure its using the correct COM port
