IT bus (1-Wire)
1-Wire bus with RJ11 connector to connect sensors to the Poseidon unitThe bus from Dallas Semiconductor company, which is designed to connect several sensors on a sort distances. The bus contains power supply and one data cable, it is not suitable for places with EMC disturbance.
# Maximum wiring length : 10 meters of total lenght
# Supported sensors: temperature, humidity and other sensors (>> The list of sensors in out assortment)
# Number of sensor on 1-Wire bus: Maximum of 10 sensors (see the device model)
# Sensor power supply: 5V/50 mA over RJ12 connector
# Sensor consumption: Power supply from the bus is sufficient for all connected sensors
# Communication cable: phone cable - 4-wire (2-wire in special cases)
# Alarm setting: Controlling values in the safe range, setting via Poseidon Flash setup
# Sampling period: 800 ms to 10 seconds (according to the number of connected sensors, 10 seconds for 41 sensors)
# Sensor address: Automatically, each sensor has its unique address
# Detection of sensor disconnecting: Yes, disconnected sensor responds "-999.9" value.
# Sensor disconnection alarm: Disconnecting of sensor causes Alarm status if sensor indicates alarm (value out of safe range).
