The Racal 1256 / J200-145 Switching System Ethernet Interface module integrates Racal switching systems with Ethernet networks, enabling remote control and data transfer across distributed test environments. This interface card transforms the Racal 1256 mainframe—a 2U rack-mountable, high-density switching chassis—into a networked instrument compliant with LXI Core 2011 standards and SCPI command protocols.
