| Abstract: | This paper describes in detail the design idea and operation principle of non-standard baud rate serial system based on PC104 bus, and solves such key techniques as non-standard baud rate generation, operation reliability at limiting environments and electromagnetic compatibility, etc. The baud rate of module could be up to 614.4kbps, while the environment temperature is from -55℃ to 125 ℃. The experiment results prove that the module could be compatible with PC104 criterion in code level and achieve all design goals in limiting conditions. |
