The needs for the miniaturization and reduction in cost of industrial equipment such as manufacturing equipment and inspection equipment is increasing year by year. In addition, the number of cases in which space-saving PCs and notebook PCs are installed as controllers and operating terminals is increasing. Although general PC peripherals have transitioned to USB and Ethernet connections, many pieces of industrial equipment such as barcode readers, modems, and measuring instruments use the RS-232C and RS-485 communication standards. It is becoming more and more difficult to find PCs equipped with communication ports that support these standards on the market.

The new products that we are introducing at this time can be used to perform data communication between the latest PCs and industrial equipment using the RS-232C (or RS-485) communication standard. This makes it possible to develop compact and low-cost industrial equipment that makes use of PCs.
