Communication architecture

In the Integra Classic architecture, control is centralized at the main computer (V20), located in the office and connected to standard I/O devices (e.g., screen, keyboard).

Each house has an IntraE Computer (fanless) that receives commands from the V20 to read/write values to the Modbus registers of RIO devices.

The Spider hub converts RS232 communication from the V20 to RS422, which supports long-distance data transmission. At the house, RS422 is converted back to RS232.
