Overview

The YOKOGAWA VF702 is a specialized network interface card designed to connect a control system to a 10BASE-2 Ethernet network. This card is primarily used in industrial automation applications where reliable and high-speed data transmission is crucial. The VF702 provides a bridge between the high-speed PCI Express bus within a computer and the slower, but robust, 10BASE-2 physical layer.
