Abstract

A technique for collectively setting a factory mode of operation of a monitor offers adjustments or modifications for particulars of mode data to meet user requirements, by transmitting a set of factory mode timing data from an external controller to an electrically erasable programmable read only memory using a serial interface data communication. A factory mode data transmission process includes the steps of transmitting a start data signal to a microcomputer in a monitor when a storage key input is fed to the external controller, repeatedly sending the timing data until a mode end signal is input and sending a mode end data to the microcomputer when a mode end signal is input. In addition, a factory mode data receiving process includes the steps of sending back the start data received to the external controller, storing mode timing data received into a factory mode address reserved in a memory in the monitor and ending the reception of mode timing data when mode end data is inputted. Consequently, any operation mode according to user requirements is able to be set in a monitor, without modifying a pre-installed program in a microcomputer housed therein, at a low cost.
