Ergometer
Type er900L
Appendix A: Interfaces
The ergometer er900L features a number of interfaces. Data can be transmitted or received
by the ergometer in analog or digital modes. Complete external control of the ergometer from
a PC or ECG is possible via these interfaces. These same interfaces also capable of trans-
ferring information to external devices (PC or ECG). ergoline provides a wide palette of
control variations using a variety of control protocols with a combination of analog and digital
signals. These protocols permit the ergometer’s connection to practically all ECG units on
the market that have an ergometric program. You will find the interface protocols in this ap-
pendix.
