DNx-SL-501-804 – RS-232/485 Serial Communications Interface

RS-232/485 Serial Communications Interface


The DNx-SL-501-804 are 4-port serial communications layers that offer fully isolated serial interfaces, software-configurable as RS-232 or RS-485. The DNx-SL-501-804 is a special, high speed version of the popular DNx-SL-501 board.



  • Arbitrary baud rate selection (0.01% accuracy)
  • Max speed of 256 Kb/s for RS-232 and 4 Mb/s for RS-485
  • J1587/J1708 support included
  • Each port is software-configurable as RS-232 or RS-485
  • Completely independent bit rate settings for every port
  • 350 V isolation between ports, ports and circuitry; 15 kV ESD
  • Includes UEI-RSS Remote Serial Server application, Windows and Linux versions

The DNA/DNR-SL-501-804 is an ideal solution for connecting serial based data acquisition devices to the Ethernet as well as interfacing to a wide variety of serial based devices and legacy DAQ systems. In addition to standard serial I/O features, the DNx-SL-501-804 offers a series of additional functions such as:
  • Fully customisable baud rates
  • Automatic in-hardware or software flow control
  • Asynchronous event mode
  • More
