OpenLDV™

The OpenLDV driver interface provides a unified Windows driver interface for sending and receiving low-level LonTalk® messages through Echelon's family of network interfaces, including:

  • PCLTA-20
  • PCLTA-21
  • PCC-10
  • U10/U20 USB Network Interfaces
  • i.LON 10 Ethernet Adapter
  • i.LON 100 Internet Server
  • i.LON 600 LonWorks/IP Server
  • SLTA-10 Serial Network Interface

When used with the i.LON 10 and i.LON 100, the OpenLDV driver software provides outstanding security including RC4 encryption, MD5 authentication, and protection from replay attacks, as well as transparent, fault-tolerant session recovery when the IP connection or power to the i.LON is interrupted.

Uplink connections—in which a remote network initiates a call, either dial-up or broadband, to a service center—are also supported. Uplink connections are commonly used in large remote access systems where hundreds or thousands of sites report back to a single service center.

Network tool installer programs usually incorporate the OpenLDV Installer; however, if it's not included, you can download and install the OpenLDV Installer separately.

LNS vs. OpenLDV

Most of our customers find that developing PC-based network tools is simpler and less time-consuming when they use our LNS® Network Operating System software. LNS based network tools also have higher performance levels than those that use OpenLDV. Need help deciding whether you should develop your network tools with LNS or OpenLDV, just contact your Echelon sales representative or request it online.
