The DNx-SL-504 has 4-port serial communications interfaces for Cube and RACKtangle I/O chassis. Each port may be independently configurable as RS-232, RS-485, RS-422/423 as well as set for synchronous communications. Each port is fully isolated from the other three ports and from the Cube or RACKtangle chassis. The board is an ideal interface to a wide variety of serial based data acquisition and control interfaces as well as general purpose serial I/O.
The DNx-SL-504 supports most popular synchronous serial communication protocols, including HDLC and SDLC. The RS-485/422 implementation provides transmit and receive, data and clock interface while the RS-232 configuration also supports standard CTS and RTS signals. The maximum transfer rate in RS-485/422 and RS-232 modes are 4 Mbaud and 230 kbaud respectively.
The DNx-SL-504 support standard asynchronous serial transfer rates up to 1 Mbaud in RS-485 mode or up to 230 kbaud in RS-232 mode. It also supports communications at 12, 12.5 and 50 kbaud with better than 0.1% data rate accuracy.
