MCM-RS232 Microcontroller Decoder Module
MCM-RS232 Microcontroller Decoder Module
When combined with the EM2 Receiver Module and the Ferrite Antenna, this module provides time information in standard RS232 data format via a serial interface. External buffering to full RS232 levels is required and can be achieved using a proprietary RS232 level shifter IC. The advantage of the module compared to direct host decoding of the receiver output is the presence of exact decoded time information all of the time and no processing overhead.
The module also features a real time clock that recalibrates itself against the Atomic Radio Time Signal when it synchronises with the Atomic Radio Time Signal.
