 +
|author=[[User:Zelenka|Zelenka]]
 +
|intro=The Variodyn D1 system can be controlled via commands transmitted by ethernet. The protocol used was designed around 1993 to handle new communication requirements. As initially designed for serial communication the protocol has a robust resynchronisation ability, and a weak checksum algorithm which can be implemented easily on small microcontrollers. Nowadays, the protocol is used inside a TCP channel to communicate with a controlling computer via ethernet. The TCP channel provides a session layer and also error correction and retransmission, so the weak checksum algorithm of the protocol itself is no longer a drawback.
