Abstract
System of high-speed data transmission to terminals which operate at low speed, which comprises: a communications control module in accordance with the BITBUS standard with a microcontroller of the 8044 family connected to a communications module which comprises a double gate RAM memory which communicates with a protocol converter module which comprises a Z80 microprocessor controlling the communications along the slow channels, a memory capacity to maintain four complete communication tasks at low speed in execution, for the process of transmission and generation of a character-orientated protocol for the output circuits to the terminals. Of application in airport remote indicators.
