1. LEDs: "RUN" - indicates appliance connection status to the main module, "ERR" - indicates appliance lost connection to the main module.
2. "Humidity & temperature sensor" - Operating temperature: −40… +125°С; RH operating range: 0 to 100%; T accuracy: ±0.4°C in –10 to 85 °C range; RH accuracy: ± 3% RH in 0 to 80% range.
3. "TR" - is the the nearest switch to CAN inputs. This switch should be turned to "ON" on position if the sensor is the last sensor in the CAN chain. The last sensor in long chain with length more then 10 meters, terminator should be in "OFF" position.
Example 1: We have 1 CAN sensor connected to the main module VT8101 on the " CAN 1" 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" position.
Example 2: We have 5 sensors or modules connected to the main module via the " CAN 1" bus and a sensor or module bus. The sensor is not the last sensor in a chain, for example, it is located in the middle of teh chain. In this case, the "TR" switch must be in the "OFF" position.
Example 2: We have 5 sensors or modules connected to the main module via the " CAN 2" bus. In this case, the 2nd The sensor is the last sensor in a chain. The "TR" switch must be in the "ON" position.
4. "CAN" - two equivalent digital connectors RJ12 for the connection to the master module, CAN sensors or CAN extensions on a CAN bus, with auto-sensing.
