I'm a newbie with the Motorola ACE3600 and have an issue with data retention. These RTUs have a battery backup but if the AC is down long enough for the battery to discharge fully, as far as I can see... all data is lost. The CPU lithium battery maintains the program code, but none of the data. Is there a way to retain some data in these units? Perhaps I am missing something simple. The manual does mention optional SRAM for the CPU, but I'm not sure I really need it. It seems odd to me that not a scrap of data is retained on these. Thanks!
