All SISGEO digital sensors (IPIs, Tilt-meters, RDSs, H-Level etc..) use the serial RS-485 communication protocol.
The SISGEO digital sensors are joined through an electrical cable, so only one cable is used to take reading.

In agreement with Customer, they are configured in factory for:

• Calibration parameters
• Serial number
• RS-485 andress. Each digitized sensor has a univocal address also reported in a label on the cable.
• Powering type:
         - always on (all digitized sensor switched on together). Faster solution, but high power consumption.
         - timed (the sensors are powered and switched on one by one). Reading of the chain take a little bit more time than "always on", but the power consumpion is lower
• Measuring units
