The sensors will automatically be detected on power up or a Detect Devices button on the summary page can be selected when logged into the unit. Splices are highly discouraged in the communication lines but if they are necessary they must be done using the appropriate sized butt splice or soldered together and in both instances should have shrink tubing encasing the joint. The exact math for calculating the maximum stub length is one of those things best left to a PhD. About Us However, for best performance with our Modbus RTU sensors, the cable should be well shielded and have an impedance of 120 ohms. The subsequent 4-wire smokes will essentially daisy-chain to the previous one. However you still need power and ground. The wiring on the Daikin communication network, known as the D-III network, runs in a daisy chain configuration from the outdoor unit to the indoor fan coils on a heat pump system or to the branch selector boxes on a heat recovery system. Daikin communication is a 16vdc communication circuit. Since DC voltage runs on the outside of the conductor it is not recommended to run solid thermostat wire as the surface area is minimal and can cause communication errors as well. Connect the speaker level inputs and as soon as you turn on the factory audio system the LC2i will power up as well. If you have over 1.75” of space above your drywall, or, if you only have a small obstruction (like a pipe or a wire) in your way, this will be the fastest and most straight-forward installation method. There's a single controller that daisy chains to 4 dampers and 3 thermostats. These will daisy chain the outdoor systems to a centralized controller(Bacnet, LON, Itouch controller or Itouch Manager). The Remote Control Bus Hub provides eight parallel ports for the connection of remote control devices to an Audia® or Nexia® system. *Includes Keypads, RF Receivers, Zone Expander/Relay … More often than not the problem is a loose connection, the wire did not get striped correctly or there were improper splices in the wiring. Stranded wire has more surface area than a solid wire of the same gauge and provides for better communication. Specifically, it is for sensors that use RS-485 communication and Modbus RTU protocol. The communications module voltage requirement is 24 Vdc ± 10% and should be sourced from a high quality supply (6 watts is the burden of the CAM) . You daisy chain the adapters (Wire #7) together and then you go to the control panel. Writing the Setup Program shows you how to use DirectSOFT to write the remote I/O setup program.
