Open RMDU File

The RMDU file extension is known as a Remote Master Device Upgrade file which was developed by JP1. This type of file is primarily associated with Remote Master by Hifi-Remote. It's a computer programming language used to program any remote that is capable of accepting the JP1 protocol. RMDU files are simple ASCII text files which consist of a property list. The property list contains information on which commands use which signals, the shape, and color of the device button. But let's take a closer look at these files.

The Remote Master Software

Remote Master is a software program that was specifically designed to work with RMDU files. It is one of the ways to open and use these files and is compatible with a myriad of universal remotes from different manufacturers. Upon download and installation, the user can freely open, read, and edit RMDU files to customize their remote controls. For those interested, the software is available for download from the Hifi-Remote website.

Importance of JP1 Interface

In the world of universal remotes and RDMUs, the JP1 interface is king. Named after the 6-pin connector found in many universal remotes, this interface is what allows the exchange of information between the remote and a PC. The JP1 interface is what allows the customization of remotes using RDMU files. More can be learned by visiting the planet-rcs.de website.

This simplifies their modification since no special software is required. However, the use of a code editor like Sublime Text or Atom might prove more convenient due to their features like syntax highlighting and auto-completion. There's a great article on text editors on the w3schools' website.
