1.2 Input Ports and Sensor Compatibility
LeNETmobile has capability to monitor 8 digital and 6 analogue sensors with its input ports that are
grouped as digital ports (A1-A4, D1-D4) and analog ports (D5-D10) and are compatible with a variety of
sensors.
- See Appendix-A for details about specification of the sensors compatible with LeNETmobile -
The following table shows LeNETmobile ports with different configuration modes and sensor
compatibility:

Note:
see section 2.2 “input ports setup” on how to setup for different configuration modes.
1.3 Data Management
LeNETmobile can operate on two modes: Meteorolical or Energy metering applications. Data is sampled
every second for Meteorological and Wind Applications. For Energy applications a discrete count system
is used. Data is grouped every 10 minutes in averages, totals or other statistical values depending on
application.
Table 1.3 shows the raw data type for LeNETmobile ports. Notice that some ports (A1-A4, D1-D6) have
more than one form for raw data, which is preset at the factory depending on the application.
