DNx-SL-501 – 4-port, RS-232/485 serial communications board
4-port, RS-232/485 serial communications board
The DNx-SL-501 are 4-port serial communications boards that offer fully isolated serial interfaces, software-configurable as RS-232 or RS-485. DNA/DNR-SL-501 supports up to 2 Mbit/s transfer speed in RS-485 mode or up to 256 Kb/s in RS-232 mode.
Features
- 4 independent ports
- Each port is software-configurable as RS-232 or RS-485
- Compatible with Half- and full-duplex support
- Max speed of 256Kbit/s for RS-232 and 2 Mbit/s for RS-485
- Completely independent bit rate settings for every port
- 350V isolation between ports, ports and circuitry
- Compatible with RS-422 networks when used in RS-485 mode
- Half- and Full-duplex support for RS-485
- Includes UEI-RSS Remote Serial Server application, Windows and Linux versions
Software for the DNA/DNR-CAN-501 series is provided in the UEI Software Suite. A high-level easy to use API is provided for Linux and most real-time operating systems, and the UEIDAQ Framework for Windows which provides a comprehensive, easy to use API.
In addition to standard serial I/O features, the DNx-SL-501 offers a series of additional functions. These functions include:
- Fully customizable baud rates from 300baud to 2Mbaud
- Programmable inter-character delay
- Programmable inter-frame delay
- Automatic repeat of the last frame if new data is not sent from the host on time
- None/Even/Odd/Space/Mark parity in 8-bit mode and per-symbol programmable in 9-bit mode
- Automatic in-hardware or software flow control
- Asynchronous event mode with loop closure in 100us
- Echo suppression in half-duplex mode (for 422 mode)
- Timeout programmable in 10us, 100us or 1ms intervals
