1. LEDs: "RUN" (green) - indicates that the appliance is correctly connected to the main module, "ERR" (red) - indicates an error, the appliance lost connection to the main module.
...
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 teh the chain. In this case, the "TR" switch must be in the "OFF" (up) 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.
