Abstract : The transmitter distributor is a general purpose transistorized data synchronizer. Therefore the system has the capabilities of synchronizing data transmission between a number of transmitting and receiving systems. The main function of the distributor is to control the flow of data between Teletype equipment and various digital systems. The transmitter distributor is capable of transferring up to 8 channels of parallel data when operating in direct parallel to parallel modes or parallel to serial modes. Only five channels of data can be transmitted in the serial to parallel modes since the present Teletype equipment transmits 5 data bits per word. The Teletype equipment governs the speed of data conversion. The present speeds are 60, 75, or 100 words/minute. Should other serial systems be employed that are faster than the Teletype equipment, or if faster Teletype systems are installed, the transmitter distributor will be capable of converting data at these faster speeds. The rate generator and monostable delays would be recalibrated to synchronize the speed of data transmission between input and output. (Author)
