The RTC module stores a copy of the configurationparameters that can be transferred to another unit with minimal downtime.The memory module functionality in the RTC chip operates as follows:1. When plugged into a C445/Base Control Module for the first time, the C445 will writeits configuration to the non-volatile memory on the RTC module continuously.2. When plugged into a different C445/Base Control Module, the RTC module willdownload the configuration to that new C445/Base Control Module. Oncedownload is completed, the new C445/Base Control Module will begincontinuously writing its configuration to the memory on the RTC module.3. Unplugging an RTC module and plugging back into the same C445/Base ControlModule will simply result in resuming normal operation. No configuration downloadfrom the memory module to the C445 will take place.4. The RTC module uses a non-volatile memory to store the configuration parametersof the host C445/Base Control Module device.
