2. © 2010 UEI, Inc. All Rights Reserved www.UEIDAQ.com Overview The UEISIM is a Linux based system that runs Simulink models. UEISIM Desktop allows remote monitoring and parameter tuning while a model is running.

UEISIM Desktop: A client written in C#, C/C++ or LabVIEW can display the models signals and parameters without Simulink being installed. Signals and parameters are also accessible via a web page.
