GE’s Multilin™ D400 is a secure, substation-hardened gateway that collects metering, status, event, and fault report data from serial or LAN based Intelligent substation devices. The D400 summarizes data from the substation devices and makes it available locally/remotely through a standard secure web browser (HTTPS).

The Multilin D400 supports serial and/or LAN connections to SCADA masters. TCP/IP network connections are supported over the built-in Ethernet and the modem interface.
