The DNx-CSDB-509 are 8-port serial communications interfaces for Cube/RACKtangle I/O chassis respectively. The boards offer fully isolated software-configurable CSDB (Commercial Standard Digital Bus), RS-232 or RS-485 interfaces. The board is an ideal interface to serial based avionics as well as general purpose serial I/O.

The DNx-CSDB-509 support both 12.5 kbaud and 50 kbaud data rates in CSDB mode as well as transfer rates up to 1 Mbaud in RS-485 mode or up to 256 kbaud in RS-232 mode. It also supports communications at 12, 12.5and 50 kbaud with better than 0.1% data rate accuracy. Baud rates based on integer divisors of 4.125 MHz or 1.8415 MHz are also supported. Based upon an industry standard UART on each port, the board supports both half- and full-duplex modes for RS-422/485 operation.

The DNx-CSDB-509 are compatible with a wide variety of legacy avionics devices. The board support RS-422 point to point or network applications when used in RS-485 mode and provide 200Ω software selectable TX and/or RX termination for RS-485 communications. In RS-232 mode, the layer provides TX/RX as well as the standard RTS and CTS hardware hand shaking required by many external serial devices.

The DNx-CSDB-509 is supported by the all popular operating systems and programming languages with a powerful, yet easy to use API. Window users may also take advantage of the UEIDAQ Framework which provides an extremely simple and complete software interface for programmers as well as supporting most data acquisition and control applications (e.g. LabVIEW, MATLAB).

All connections to the CSDB-509 are through a 62-pin dSub connector. However, the optional DNA-CBL-62 series cable and the DNA-STP-50 breakout board bring out each port to easy-to-use 9-pin dSubs.
