Datek uses synchronous data transmis- sion, which means that each bit of data is checked very carefully. Even the smallest deviation from the norm is detected, and then the entire data packet that has been received is rejected. Each system has a unique ID code. If the transmitter’s ID code does not match the receiver’s, radio communication will never be established.
Both the protocol and its checksum are digitally verified by dual processors using different software. This provides what is known as a redundancy check.
If the processors interpret the protocol differently, they immediately shut down all outputs. Such safety features as digitally verified transmission and redundancy checking are just two of the innovations which Datek has pioneered in the area of radio remote control. Since its founding in 1979 Datek has focused on developing safe radio remote controls, something we still do and will continue to do!
The receiver’s frequency is adjusted to the required frequency band. For frequency-shift transmitters, the receiver scans the frequency band until it finds the relevant transmitter with the correct ID code and protocol.
