Extension interface (EXT)

The plug of the proprietary expansion bus is designed as USB type B but uses a manufacturer
specific protocol.
The configuration parameters are stored directly on the device. In addition, a configuration
stick can be connected to the expansion bus to save data externally, in example to exchange
defective devices easily.
Danger of damaging the device.
Do not connect any USB devices!
