High Performance XMC Serial Communications Adaptor

February 2012. Concurrent Technologies announces the latest addition to their range of communication XMC mezzanine cards. The XM RS1/20x is a low power asynchronous serial communications adaptor supporting either the industry standard RS232 interface, RS422 differential interface or the RS485 multi-drop interface. The product is ideally suited to expand upon the number of serial ports of the host processor board and can be used in a wide range of industrial, telecommunication, commercial, financial and defense applications.

The XM RS1/20x is a single-size card and is compliant with the XMC (Switched Mezzanine Card) specification; it can be installed onto XMC sites on appropriate host boards such as Concurrent Technologies’ 2nd Generation Intel^® Core™ i7 based VME, VXS™, CompactPCI^® and VPX™ boards. Like the XM RS1/20x, Concurrent Technologies’ ranges of XMC host boards are available in commercial and extended temperature versions, and some are available 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 IO, via P4, can optionally support an additional four RS232 or RS422/485 ports dependant on variant. All serial ports provide TXD, RXD, CTS, RTS, DCD, DSR, DTR and RI signals.

Glen Fawcett, CEO for Concurrent Technologies, commented, “The XM RS1/20x serial communications adaptor complements our range of Single Board Computers utilizing the 2nd generation Intel^® Core™ microarchitecture and demonstrates our capability to further support our customers with a rich complement of peripherals.”

To simplify the board’s integration many popular industry standard operating systems are supported including Windows^® XP, Windows^® XP Embedded, Windows^® 7, Windows® Embedded Standard 7 and Linux^®.
