- Angle brackets for wall mounting
Measure, control and regulate automatically and independentlyALLNET has been pursuing the concept of intelligent control of processes in building technology via network and Internet for years.
Intelligent building technology not only offers more comfort, but also actively promotes the saving of energy costs.
Centrally controlled and accessible via network / internet, ALLNET building automation products enable intelligent building technology independent of time and location.
Multiplexing - Note on operating several sensors on one sensor portBasically it is possible with the ARM and MIPS based systems, in contrast to the ALL3000/4000, to operate more than one sensor on one physical port.
The hardware requirement is that the sensors have 2 RJ45 connectors, so that the sensor signal can be passed on to the next sensor.
The total cable length of 100 m does not increase.
So that the sensors can also be clearly identified by the devices, it is necessary that these have different I2C chip addresses and IDs on the software side.
Sensors with the same chip address and adjustable
ID can be combined.
For sensors without adjustable address only 1 sensor type can be connected per port or via ALL4404 8x multiplexing HUB.
