I just watched a YouTube video posted by M today advising dealers about the proper way to update firmware, wherein a special Meridian serial-to-RJ45 cable is said to be necessary.

Does anyone know about an available adapter that would allow those of us located hundreds of miles from a dealer to update using our connected ethernet cables?
