LAST UPDATE: NOV 2021

The OpenLDV Network Driver for Windows provides IzoT, LON/IP, and LON tools and applications with an open and unified Windows software interface for sending and receiving messages through LON/IP and LON network interfaces.  The OpenLDV driver supports network interfaces from Dialog and supports compatible network interfaces available from other manufacturers.  

OpenLDV includes integrated drivers for the following Dialog network interfaces: 

  • SmartServer IoT Edge Server with Remote Network Interface (RNI)
  • U10, U20, U60, and U70 USB Network Interfaces
  • SLTA-10 Serial LonTalk Adapter

OpenLDV also works with Renesas legacy network interfaces such as the SmartServer 2, i.LON 100, i.LON 600, IzoT Router, PCC-10, PCLTA, PCLTA-10, PCLTA-20, PCLTA-21, and SLTA/2.

OpenLDV is supported on the following versions of Microsoft Windows:  Windows 11, Windows 10, Windows Server 2019, and Windows Server 2016. 

The following three versions of OpenLDV are available:

  • OpenLDV Network Driver – standalone version of OpenLDV that you can use to add a LON network driver to a Windows computer.
  • OpenLDV Embedded Installer – silent installer for the OpenLDV network driver that software developers can embed into their software installation packages to add LON network driver support to their software.
  • OpenLDV SDK – example source code for software developers using the OpenLDV Network Driver
