4.2 Input Ports

The Input Home tab provides an overview of all available input connectors on the SmartSampler2. From here, you can enable or disable entire input interfaces and navigate to their detailed configuration tabs.

🔌 Available Input Interfaces

The SmartSampler2 supports the following input types:

• Analog / UART
  • 6 configurable pins, each usable as Analog (0–5 V) or as part of UART1–3.
• I²C
  • Standard I²C bus for digital sensors (3.3 V / 5 V selectable).
• RS-232
  • Standard single-ended serial interface.
• RS-485
  • Differential bus supporting Modbus RTU sensors.
• SDI-12
  • SDI-12 compliant multi-drop interface for environmental sensors.
• Module
  • Expansion port for additional hardware modules.

⚙️ Enabling Interfaces

• Each connector has a toggle switch ON/OFF displayed below the corresponding port.
• Turning a port ON activates the electrical interface and makes its configuration tab available.
• Turning a port OFF disables the interface, conserving power and preventing unintended communication.

💾 Save Settings

• Press Save after making changes to ensure the interface selection is stored in EEPROM.
• Saved settings persist after restart.

📌 Notes

• Only enabled ports consume power; disabling unused interfaces is recommended for field deployments.
• The graphical view of connectors matches the physical layout on the SmartSampler2 housing, making it easier to identify ports during wiring.
• Each interface requires separate configuration in its respective tab after being enabled here.
