Smart logarithmic dimming curves
Allows the default dimming curve of the analog inputs to be changed from linear to
quadratic, cubed or biquadratic dimming curves in order to achieve the the desired
dimming behavior.
Adjustable background/fall back color
In case of absence or loss of the control signal, a fall back color can be set for every
DiGidot C4. You can also set the delay time before the fall back activates.
Online/offline firmware updates
We offer online updates easily within the user interface and offline updates in case that
the DiGidot C4 controllers are not connected to the internet. You can find the firmware
over at https://digidot.eu/c4/digidot-c4-updates/. Use the download link to get the file.
You can upload the new firmware at http://10.254.254.254/fwupdate.htm. You can also
change the '10.254.254.254' in the URL into the IP Address of your DiGidot C4 device. It
is also possible to upgrade or downgrade multiple devices simultaneously.
Output limiter
You can limit the output power to a pre-set brightness. There are two ways to do this.
Brightness limiter
This option limits the individual channels to a specific percentage. This means
that every channel or LED will never exceed this percentage.
E.g.: Limiting brightness to 50%, means that all individual channels can never
exceed 50% but the control range per channel will remain the same. Effectively
the percentage is applied to the input value for each channel.
Adaptive power limiter
This option limits the total average output of all channels combined to a specific
percentage in order to decrease total power consumption. Individual channels
my still output up to 100%.
E.g.: Limiting power to 50% means that half of the channels can output 100%
and the other half at 0% or all channels at 50%, etc.
In case you would try to output all channels to 75%, the output of all channels
would be automatically limited to a total 50%, but will maintain ratios relative to
each other.
16 bit dimming output
Whenever high resolution dimming is required and supported by your IC, two input
channels can be combined to one output channel in order to convert 8 bit to 16 bit
dimming.
Configure LED color order
In case a LED product has an alternative order of LED chips or dyes, you can change
the order of control channels easily in the user interface. The interface uses the default
color order of the selected IC.
*Some functions are limited to specific versions, see C4 comparison on page.
