Abstract

Remote realistic interface experimentation using the Emona Datex board By Aboluwarin O.O., Kehinde L.O., Ayodele K.P., Ishola B.I. Department of Electronic and electrical Engineering Obafemi Awolowo University, Ile-Ife, Nigeria AbstractPast work on remote experimentation with the Emona Datex Board largely interacted withonly one experiment already fixed by cable hardware at the remote end. This can be veryrestrictive and inflexible. In this paper, remote experimentation is being designed for theboard in such a way that experiments can be altered and reconfigured by students throughremote node to node cable connections.Remote reconfiguration of the circuit for multiple experiments on the actual Emona Datex isfacilitated through the use of a National Instrument (NI) SCXI 1169 100-channel switch arrayand a web service implemented with C# that allows the switches in the array to be sharedby multiple labs. Data acquisition is achieved through a NI USB-6215 DAQ card controlled bya C#.NET experiment engine working with a custom-built LabVIEW dll for each experiment.The graphical user interface of the lab client is an exact replica of the Emona Datex boardwith all its controls (switches, knobs and connection nodes) activated programmatically suchthat they can be controlled remotely through a webpage. It is implemented using JavaFX1.3.In this paper, we have considered the iLab implementation of four basic telecomsexperiment (Amplitude Modulation, AM Demodulation, DSBSC Modulation and DSBSCDemodulation) but we have used the Amplitude Modulation lab as a specific case study. Ithas great potential for students in Communications Engineering.The lab is built on the iLab Shared architecture, which provides a framework for rapidremote-lab development and deployment, and uses a three-tiered architecture comprisingClient, ServiceBroker and LabServer. It is built on the NI Elvis System and Emona Datex add-in module which is fully integrated with the NI ELVIS platform. The beauty of this work isthat even though the student’s interface is the replica of the Emona board, the art ofactually making realistic and visible virtual cable connection remotely will add to improvedpedagogy and understanding.The technology and issues concerned with the development and usage are discussed.Furthermore, the experience gained in developing, testing and using the system, as well asfeedback from students are also presented.Keywords: Telecoms, JavaFX, Emona Datex, ilabs, Elvis
