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
