Before I purchased, I inquired if it was suitable as a replacement for the redundant EM-406 and was told it was. However information about software changes like Baud rate will be required before it will work as a change over replacement so it was not a straight forward replacement as expected. We have not completed the software changes to make it work yet so I hope I am not premature providing this requested feed back. Relevant info at the time of inquiry before my purchase would have been appreciated as I had not booked my software writer to alter code.
