5 Communication ports
This chapter describes the communication ports in the back panel of the Corival:
RS232 (two ports for RS232-in and loop connection RS232-out)
Analog in/out
5.1 RS232
The Corival has two RS232 connectors for loop-connecting a number of Corivals and for
communication with a personal computer or an ECG device. When the ergometer is
controlled externally always use the RS232-in port.
Via RS232 an ergometer can be monitored and settings can be entered with a computer.
5.2 Loop connection
It is possible to control several Corival ergometers with one external device using RS232.
Connect the RS232-in connector to the external device. Connect the RS232-out connector to
the RS232-in connector of the following Corival ergometer, and so on. The maximum number
of Corival ergometers that can be connected in this way is 8. Use the device number option in
SYSTEM PARAMETERS to give each Corival a unique number. In this way each Corival
can be controlled separately, using the LEM software.

5.4 Analog in/out
