How does the CMS data acquisition interface work?
Connecting and configuring the CMS monitor
Plug the end of the RS232 cable into the connector at the rear of the monitor
labelled "RS232" and the other end into the 9-pin serial input connector of your PC. Then switch on the
monitor and press [Monitor setup] -> [Configuration Mode] -> RS232. Make sure that port #1 is in "Computer
on" state and select the baud rate to be used. We recommend that you always use "38400" as baud rate since
this is the highest one supported by RS232 interfaces. The corresponding TX/RX must be set to Low/High. Store configuration
settings. Leave configuration mode and let the monitor start up as usual. Please consult the monitor manual for details.
Controlling monitor data acquisition with Dataplore
Select "Open Serial Port" from the Dataplore "File" menu. A panel will appear where you must
tell the program the serial port which you connected the monitor to (usually this is COM1 unless it is used
by another external serial device) and the baud rate (38400) you have chosen when you configured the monitor.
Then click into the button "Init" and wait until a list of messages appears in the tune list at
the bottom part of the window. The messages available are either signal sample data (Typ_SpiCW)
or numerical data like heart rate (TYP_SpiNU) and depend upon the parameter modules (ECG/Resp, Temp, SpO2/Pleth, ...)
currently plugged to the monitor. Select the messages to be recorded from the list and start data acquisition by clicking
the "OK" button.
Note: The number of data (signal sample data or numerical data) which can
be recorded in realtime is limited by the data or transmission rate of the RS232 interface.
A new Dataplore window called "serial communication" will open in the background.
You can put it into the foreground by clicking onto its icon in the Windows task bar.
This new window is divided into a number of sub-windows showing the course of the signals
and numerical data you requested. You can change the length of the time intervals displayed in
the windows from 5 seconds to 30 seconds. The duration of the data acquisition (log time) is also displayed.
Note: You can change the colours of the signals by assigning them other RGB values in the Dataplore Option | Preferences
| Colourmap dialog.
Serial port: Initialization dialog:
Stop data acquisition by pressing the "Exit" button or by closing the window. It will take some
time for the communication between the monitor and your PC to finish and for Dataplore to load the signals into the signal
icon bar for further processing. The longer the total duration of the data acquisition
and the more messages you requested the more time it will take to load the signals.
The signals recorded from the interface are then accessible from the signal icon bar for displaying, processing and saving.
Consult the online Dataplore user manual for more information on the numerous features and possibilites of this software
package.
