PURPOSE:To check a computer device by providing a light emitting means to a microcomputer device to output the coded digital data, i.e., the checking result. CONSTITUTION:Various types of analog input set at each reference state are checked through a connector terminal. These checking results are turned into a series of coded digital information based on a prescribed rule and applied to a light emitting means 4. The means 4 blinks based on the received digital information and produces the optical signals. These optical signals are received by a light receiving means 5 through a light leading part 5 and converted into the electric signals. A checking device 10 analyzes the electric signals and confirms that the checking result output is equal to a prescribed level. Thus no connection of a connector is required and the checking jobs are simplified. |
