Abstract: In order to monitor the multi-parameter in hospital operating room, the application of GM8125 in data communication system for the information board is introduced. AT89S8252 is adopted for the main MCU. Due to realizing COM extension by using GM8125, the multi-data is expediently integrated including the data of monitor for IT power supply, the controlling parameter for air condition, the pressure parameter of gas used in hospital, the controlling parameter for upper computer. Practical results show that the method has the characteristics of the ability of controlling easy. The ability of reducing the data line and the ability of depressing system resources of the main set. When reliable data communication is accomplished, the suited time requirement of the system will be fully satisfied.

Key words: multi-parameter monitor, serial communication, COM extension
