Master Extensions

For the Programming Interface concept, Master Bricks route messages between Bricks and the PC. To establish a connection between a PC and the Master Brick, typically the USB port is used. Master Extensions can be utilized to change the interface of a Master Brick. There are cable based and wireless Master Extensions available. From a programming perspective the different interfaces are transparent. A stack with Master Extension behaves as if every board in the stack would be directly connected to the PC over an USB connection.

This means: You can develop an application with all boards independently connected to the PC over USB. Later you can stack these boards together to stacks, add Master Bricks and cable based or wireless Extensions and you can run the previously written code without any changes.
