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 the ECG device has its own ergometry-control program and
when the ergometer and ECG – and possibly other devices such as pulmonary function measuring devices
– can be combined to form an ergometry or pulmonary function measuring station.
In combination with third party 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 in the program “Setting” under “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 un-
der “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 opera-
tion” 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 de-
vice off.
