Appendix A: Interfaces

The modular ergometer system eBike has several interfaces. Digital as well as analog data can be
exchanged with the ergometer. These interfaces thus allow the ergometer to be fully controlled from a
PC or EKG unit and they also permit a mere transfer of data from the ergometer to the EKG unit and
PC.
