Adjustable 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 download the DiGidot c4 firmware at
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.
