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.
Analog interface
PORT 2 (9-pin SUB-D)
PORT 3 (5-pin DIN socket)
PORT 1 (9-pin SUB-D)
multi-purpose port
