Rugged XMC communications adapter for military embedded systems introduced by Concurrent

WOBURN, Mass., 21 Feb. 2012. Concurrent Technologies Inc. in Woburn, Mass., is introducing the XM RS1/20x low-power Express Mezzanine Card (XMC) asynchronous serial communications adaptor for military embedded systems, as well as for industrial, telecommunications, commercial, and financial applications. The XMC embedded computing board supports either the industry standard RS232 interface, RS422 differential interface, or the RS485 multi-drop interface.

The XM RS1/20x XMC communications adapter is a single-size card and complies with the VITA XMC switched mezzanine card specification. It can be installed onto XMC sites on appropriate host boards, and is available in extended-temperature and commercial versions, as well as in ruggedized, conduction-cooled, or air-cooled, versions.

The XM RS1/20x interfaces to the host board via an x1 PCI Express link on the XMC bus. The front panel provides three RS232 ports via industry-standard 9-way micro D-type connectors. Rear I/O, via P4, optionally can support four more RS232 or RS422/485 ports. All serial ports provide TXD, RXD, CTS, RTS, DCD, DSR, DTR, and RI signals.

Software support includes Windows XP, Windows XP Embedded, Windows 7, Windows Embedded Standard 7, and Linux. For more information contact Concurrent Technologies online at
