Communication adaptor for game set

摘要

The same clock signal is applied to respective bits in a clock output port in synchronization with the transmission/reception timing. A buffer memory for temporarily storing transmit/receive data stores transmit data and receive data in synchronization with the clock signal. Data converting means comprising a CPU and a ROM format-converts bit serial data received from each of game sets into bit parallel data or format-converts bit parallel data to be transmitted into bit serial data. Receive data writing means writes the data format-converted by the format converting means into transmit/receive data temporarily storing means in synchronization with the clock signal. Transmit data supplying means supplies the transmit data stored in the transmit/receive data temporarily storing means to each of bits in a data output port after being format-converted into bit corresponding data by the format converting means in synchronization with the clock signal. Since data can be reliably transmitted in a simple circuit without using high-cost modems and the number of game sets to be connected can be increased, therefore, the present invention is applicable to a variety of games.21
