I know that there is a few version for the RCM6750 because I found out that it’s datasheet have different version. The newest is 90001191_F. I have been using the 90001191_E version for a while and only found out the 90001191_F version lately.
I found out that one of the difference between the two version is it’s backup battery current consumption decreased from 120uA to 50uA. May I know is there any other differences?
This is because I faced some timing issue when I use the serial communication (RS485 signal) on the latest RCM6750 version 90001191_F. I have no such issue when I use 90001191_E version.
