Integral Module Rack
The patient monitor has two kinds of integral module rack: 2-slot and 5-slot. The control
board includes a NIOS II FPGA. It implements protocol conversion and infrared
communication between the main unit and the parameter modules
The module rack communication board can be a 2-slot type or a 3-slot type. The 3-slot
communication board communicates the main board directly. The 2-slot communication
board is connected with and controlled by the 3-slot communication board. The 3-slot
communication board has the function of communication control. The 2-slot communication
board consists of the infrared circuit and module power circuit. The RS422 drive circuit is
located on the 3-slot communication board.
