Constructing Communication Port of Manchester Code with HSO/HSI of 8098/80cl96 KB

摘要

During development of Combined Well-Logging Meter, writers constructed a serial communication interface with HSO/HIS of 8098/80c196 KB.In this paper the operation principle and working parameters of the interface as well as hard-wave circuit of Manchester code matched with cable have been analyzed. Using this interface, a various of parameters under oil-well can be delivered to surface and then decoded and data processed by surface instrument.
