Accelerate laboratory middleware development and medical device integration with MediConnect Tester, an advanced GUI-based communication testing utility. Built using Python and Tkinter, this specialized desktop software acts as a robust diagnostic tool and simulator for testing data exchange (including ASTM and HL7 protocols) between laboratory pathology analyzers and Host Systems (LIS/HIS). The application bridges hardware and software layers by offering flexible connectivity via Network TCP/IP (IP Address & Port) and Serial Ports (COM Port, Baud Rate, and Byte Size). Designed for engineers, developers, and lab technicians, it can continuously attempt and maintain stable data streams. Whether you need to test single-direction data feeds or full query-response loops, this tool handles it effortlessly while logging raw communication packets into local text files for deep analysis.
