3 Technical Data
3.1 Interface RS232
For connecting the DCFRS industrial version to the RS232 interface a 9-pole DSUB plug is required. If
on the interface there is a 25-pole DSUB connector for serial interface, then this must be reduced to 9
contacts with the aid of a customary adapter. The interface has the following assignment:
Pin Name Function
2 RxD Demodulated DCF77 reception signal, 1 pulse per second
4 DTR negative supply voltage, only when reception service is activated
5 GND Signal ground
7 RTS positive supply voltage, only when reception service is activated
Table 1: Interface assignment RS 232.
3.2 Interface Antenna
The 4 wires on the split connection of the TTY-RS232 converter have the following function:
Color Function
yellow Connecting to the antenna (negative potential)
green Connecting to the antenna (positive potential)
brown Supply voltage antenna circuit TTY-RS232 converter connection 1
white Supply voltage antenna circuit TTY-RS232 converter connection 2
grey Cable shield
