Prototype transmission device• Prototypedevice consists of two pieces: analogue modembuilt on the base of the transmission module AVT-5085and digital controller built on the base of themicrocontroller ATMEGA8.• The software for the controller was designed with theassembler AVR and Atmel programme AVR Studio 4. Toachieve higher speed it was divided into several folders.<strong>Data</strong> are read and written through the serial port USART(bus RS-232C). The communication between the receiverand transmitter is realised through “virtual serial port” withthe SNAP protocol. The “repetition mechanism” is alsoincluded.
