Physical description

1. LEDs: "RUN" (green) - indicates that the appliance is correctly connected to the main module, "ERROR or ERR" (red) - indicates an error, the appliance lost connection to the main module.
2. "Pressure, humidity & temperature sensor" - The sensor is located outside of the enclosure for better measurement and precision.
3. "TR" - This switch should be turned to "ON" (down) position if the sensor is the last one in the CAN chain. Otherwise, the switch should be turned to "OFF" (up) position.
Example 1: We have 1 CAN sensor connected to the main module VT8101 on the CAN bus. In this case, this sensor is the only one and the last one in the CAN chain, and its 2nd "TR" switch should be in the "ON" (down) position.
Example 2: We have 5 sensors or modules connected to the main module via the CAN bus. The sensor is not the last sensor in a chain, for example, it is located in the middle of the chain. In this case, the "TR" switch must be in the "OFF" (up) position.
Example 2: We have 5 sensors or modules connected to the main module via the CAN bus. The sensor is the last sensor in a chain. The "TR" switch must be in the "ON" (down) position.
4. "CAN" - two equivalent digital connectors RJ11 6P4C for the connection to the master module, CAN sensors, or CAN extensions on a CAN bus, with auto-sensing.
