Technical specification
Funkdatenübertragung:
The radio data exchange is bidirectional and works in the 433MHz band. It is
a very narrow band radio with 25kHz band space, 64 channels divided in 8
blocks to 8 channels (block number is changeable on the device). Radio
range: 1 km on free space (more with 30cm antenna stick), high temperature
stability, immune to interference, automatic selection of an undisturbed chan-
nel. Hardware data speed between Secu-Data devices: 4.800 Baud .
