Neets Control - EcHo and EcHo Plus

EcHo and EcHo plus are 8 button control systems and are both very versatile in their use.

Several RS232/LAN ports and I/O's for controlling your A/V installation.

  • Q: The EcHo has three I/O ports. What are they for?
    A: Most people opt to use two I/O ports for controlling the projector screen – one for roll-down and one for roll-up. With the third I/O port, you are able to connect a PIR motion sensor, which is brilliant for designing eco-friendly installations. You can make the PIR turn off your installation when no motion is detected and remember to time the system so that it does not turn off too soon.
    What you could also use your I/O for is a keyboard lock, which prevents unwanted handling of the control panel.
  • Q: Can I use my EcHo to control IR devices and how many?
    A: With the Neets Dual IR Emitter PN 307-0286, the TX/IR port can be setup with two IR emitters. In case you need more IR emitters, you will need to go with a SieRRa II, AlFa II or DelTa.
  • Q: Why do both of the IR devices react to the same output command?
    A: They do so because Neets Control System sends out the same command string to both IR emitters, so if you have two similar devices using the same IR codes, they will react simultaneously.
  • Q: Is it possible to access a GUI (Graphical User Interface) with an EcHo Plus?
    A: Yes, but you will only be able to see a fixed illustration of the interface you designed for the buttons in Neets Project Designer. The buttons are interactive though with LED indication on change of state.
    For a fully configurable GUI, you will need to use a SieRRa II, AlFa II or DelTa.
  • Q: Are all the button functions pre-defined?
    A: No, all the buttons are freely configurable with the Neets Configuration Software.
  • Q: Can I use the EcHo Plus with Neets Central Control?
    A: Yes, the EcHo Plus is available in Neets Central Control.
  • Q: Is the EcHo Plus expandable?
    A: Yes, you can expand with up to two NEB modules, choose between up to two extra NEB Keypads and/or up to two NEB Level Controls and/or one NEB Port Expansion.
    For further specification, please go to our website and find Neets Expansion Bus in the product page section.
  • Q: What software should I use for configuring the EcHo Plus?
    A: We recommend that you use the latest version of Neets Project Designer.
  • Q: What should I do when I want to use the panel as Enhanced LAN expansion?
    A: Upload an empty project into the panel. This ensures that the systems are running the same firmware.
  • Q: How does extension devices communicate with the control system?
    A: The Neets Control system uses Multicast to communicate. This is done on IP address port 7979.
    • Each control system/extension device sends out a "keep a live" every 3 seconds.
    • If the control system has not received any message from an extension device for 10 sec it will indicate connection error.
    • The timeout is an individual timer for each extension device.
    • The “missing connection” indication will be removed when the connection is established and the extension device is initialized again.
    • The 10 sec timeout is reset whenever there are communication between the units e.g. when RS232 commands is transmitted or an event is triggered.
    • The control systems support IGMP, this allows the control system to only receive multicast packages on the address that it need and it also doesn't “Pollute” the entire network like UDP broadcast. In order to use IGMP the switch also need to support this.
