 Hardware

200 Series Performance Instrumentation packages should interface with our DataCenter via the same telecommunications options as the 1000Series.  The Performance Visualizations for the 200 Series follow the same general format and structure as the current 1000 SeriesVisualizations but be reduced in scope and complexity commensurate withthe reduced functionality of the 200 Series.  

200 Series systems can also be used as satellite monitoring systemsto add additional capability to complex monitoring systems based on the1000 Series product line.
