The Data Source Rack (DSR) is a rack based system that allows easy inclusion of up to 12 DSM’s (Data Source Module) at a time. The complete system contains multiple serial ports, embedded Ethernet capability and optional battery backed ram, disk-on-chip storage and clock/calendar support. This modular approach enables the user to configure as much processing power as required, with flexibility for future growth. Each DSR can support multiple IED’s. In some cases 50+ IED’s might be connected with fiber connections via external converters.

The DSR 12 contains an embedded smart Ethernet switch, which serves as the backplane for communication between DSM’s, external Ethernet based IED’s, connections to remote SCADA systems and for cascading multiple DSR-12 racks together. Communication support for both serial and TCP/IP interface. Serial interface supports flexible RTS/CTS handshaking and RS422/485 interfacing.
