DM-20/21 Device Manager

Install and replace devices on a LonWorks network—automatically!

Unlike conventional network management tools, the DM-20/21 doesn't make any network management decisions itself; instead, it works from a database created using the LonMaker Integration Tool. This lets you use a tool with a rich user interface for the heavy lifting of designing networks, and leave a small, inexpensive device on-site to manage your network.

Once you design your network, the DM-20/21 Device Manager carries out the implementation details specified by the LonMaker tool. It's true plug-and-play: great for when you can't leave a PC on-site to manage a network, or when service personnel don't have portable PCs to manage installations.
