7.3 Remote
Operation
7.3.1 Explanation
Remote operation means that the ergometer is externally controlled via the digital RS-232 interface or USB
connector, i.e. all commands for the load and blood pressure measurement intervals are transmitted from
a separate “master unit”.
This type of operation is used primarily when several ergometers are controlled from a central workstation,
the ECG device has its own ergometry-control program and the ergometer and ECG unit – and possibly
other devices such as spirometry devices – can be combined to form an ergometry or spirometry station.
In combination with SCHILLER ECG units, remote operation is the only approved operation method.
7.3.2 Prerequisites
When the remote operation mode is selected, the unit used (an ECG device or a PC) must be connected
with the ergometer via an interface cable. For our ergometers, this is a type RS-232 interface, which is
isolated to ensure the patient’s safety.
The appropriate baud rate must be selected under menu option “Setting > Interface”. The appropriate
transmission protocol must then be selected in the same menu under “Instruction Set“. The so-called
"ergoline operating mode" is stored under the setting P 10. Our own transmission protocol is located under
“ergosana”.
Information on interface and instruction set can be obtained from the operating data of the master unit.
When the settings have been correctly defined, the ergometer automatically switches to “remote
operation” when the first command comes through over the interface. The ergometry screen is opened in
the display, showing the current load, blood pressure and pulse rate data in both alphanumeric and graphic
forms. The execution of the internal programs is disabled in this operating mode.
Remote operating mode is ended by either pressing the command button “End” or by switching the device
off.

Training Program (Option)
The use of the training program requires a pulse signal receiver (Polar system), which is integrated in the
control panel. The receiver can be ordered together with the device or added later on.
