<p>This report is the result of a diploma work made at IMT at US in Linköping. The purpose of this piece of work is to investigate the possibility to design a general program for data-acquisition using LabVIEW, suiting different hardwares and connections. Great importance has been attached to communication with serialport, using bluetooth, because different wireless PPG-instruments has been developed parallel to this project. These PPG-circuits uses this type of serialcommunication. Communication with USB, GPIB and analog connection has also been examined and analog communication has been tested practically. But any serious implementation of these types in the LabVIEW-program has not been made.The paper starts with theory where LabVIEW, bluetooth, PPG, different connections and the different PPG-sensors is described concisely. Theory is followed by a"performance-part"where the course of action and the LabVIEW- program is described.The result of the work is an application in LabVIEW for communication with different PPG-sensors, where interface, protocol and file-standard/format has been designed. The program is adapted to prolonged measurements with full duplex. Measurements can be saved into ascii- or binary format, and signals can be studied carefully in graphs.Since only one PPG-sensor is fully made, a test in measurement and acquisition has been made with that sensor only. Ragarding the other PPG-instruments, the communication has been tested in hyperterminal.</p>
