nIO 1S: What Is "Broadcast Analog Input" Mode For The nIO 1S?

The nIO 1S can be set to "Broadcast Analog Input" Mode, which will accept a 0-10V dimming from a 3rd party device and broadcast it over the selected Photocell Channel.

For a dimming relay or power pack controller to track the nIO 1S analog input, the controller's "Follow Photocell Mode" has to be set to "Enabled - Both Positive and Negative".

If one looks at Control Channels in SensorView,  the nIO 1S will show as broadcasting in both switch and photocell channels.  The nIO 1S will broadcast over a Switch Channel when the mode is set to "Wallpod".

Overall, for setting up the nIO 1S to act as a 0-10V input you will need the following: 

  • nIO 1S programming will need to be changed to “mode: broadcast analog input”. 
    • This changes the nIO 1S into a 0-10V sourcing device (sourcing 1mA), which can then take a 0-10V sinking signal (from 0-10V wall switch dimmers, photocells, etc.) and translate it back over the local nLight network
    • The input translates according to the following: 10V=100% and 0.1V=1%
  • Changing the nIO 1S to this mode effectively broadcasts as an ADC, so there are a couple limitations:
    • Signal will broadcast on the local photocell channel, and cannot be broadcast globally (i.e. cannot be used for global channels)
    • Two ADC devices (or nIO 1S devices) should not broadcast on the same photocell channel
  • Devices looking to track this 0-10V input will need to be put in “follow photocell mode: enabled both positive and negative”

*NOTE:  This will only work to dim the fixtures, it will not turn them on/off (i.e. driving the input to 0% will not send a signal off command to the nLight bus).  You will typically still need a relayed device for this.
