OpenDRO is the name of the open source software that runs on the ShumaTech DRO-550 and DPU-550 products.  It is released under the GPLv3 license so that anyone can use the software and contribute to the project so long as they respect the terms of the license.  The software is constantly evolving and improving so we suggest you check the current Release Notes periodically for new features and fixes.  If you are interested in modifying the source code, further detail can be found in the Build Instructions.

The software is hosted on SourceForge where you can find the C source code as well as the binary images for each ShumaTech product.  Please look at the OpenDRO User's Guide for more information on the features and functionality of OpenDRO.
