Supporting serial RS-232 and Ethernet communications, RMCLink provides full functionality to read and write registers, read bits, and issue commands to all RMC controllers.

RMCLink comes with sample projects to help you get up and running quickly. The RMCLink help includes detailed walk-throughs and numerous code snippets.

Supported Programming Languages and Applications

RMCLink can be used from numerous programming languages and applications. It has three interfaces to make it intuitive and easy to use from any language.

The table below lists supported programming languages and applications and the respective RMCLink interface that should be used for that language. All the interfaces are included in the RMCLink download.

RMCLink includes fully-functioning example projects for many programming languages. These examples are ready-to-use and illustrate concepts such as reading positions, issuing commands, and reading plots.
