Description
DCF77 radio clock module


The radio clock C28COM was designed for operation in combination with RS232 interfaces. Besides the antenna and the DCF77 receiver, the module includes a microcontroller for decoding the DCF77 telegram. C28COM provides a Meinberg Standard Telegram that includes information on date, time and status of the clock via it's transmission line. An integrated bicolor LED signals the synchronous state of the clock and the demodulated time marks. C28COM is powered by control lines of the RS232 interface, an external power supply is not necessary.
