3.5 INTEGRA-TR HELP FILES Integra-TR Field Programming Software’s online help files are accessed by the menu bar at the top of the Field Programming window. Figure 42 - Integra-TR Online Help Introductory Screen 3.6 OPTIMIZING YOUR SYSTEM Detailed system engineering is beyond the scope of this manual. However, there are some simple tips that can be used to optimize performance of a radio based SCADA or telemetry system.
Interpreting RSSI Readings Typical values of RSSI will be in the range of -110 to -60 dBm (depending on network speed), with higher values (i.e. less negative values) indicating a stronger signal. Reliability of data reception depends largely on signal strength. Good design practice calls for a minimum 30 dB “fade margin”, based on a threshold reception level of -107 dBm (1 uV) at speed of 9600 b/s. Experience indicates that this will give about 99.5% reliability.
