Transfer protocol

All characters and/or digits are based on the ASCII standard, i.e. every reading

processed internally as an integer or float value will always be broken down into and

transferred in its individual ASCII format characters. They must then be reassembled in

the reverse process by the receiver.

Transfer rate:

Data bits:

Stop bit:

Parity:

The checksum is calculated along by the receiver by adding all received bytes up until

byte 35 and then compared with the checksum transferred from the P03.

Units:

Temperatures in degrees Celsius

Sun intensity in kilolux

Daylight in Lux

Wind in metres per second

The DCF signal can be easily interfered with. It is possible for no radio clock reception to

exist for extended periods. Therefore, only use the output time for synchronization of

another clock working in parallel in the system. For this, the second 0 should be used.
