DiGidot C4 v2.0 questions

How to downgrade a DiGidot C4 firmware version 2.0 to 1.0

Before downgrade from firmware version 2.0 to 1.0, please note that all settings of the DiGidot C4 will be lost after updating.

Follow the steps below to downgrade:

  1. You can download the previous firmware from here.
  2. Connect your DiGidot C4 to your computer or laptop and check your network settings are correct.
  3. Go to page or http://[‘IPADDRESS OF C4’]/fwupdate.htm
  4. Select and upload the downloaded file to the DiGidot C4. This will take about 6-7 minutes. Enable “Broadcast to all C4’s” if you want to downgrade multiple devices.
  5. It’s highly recommended that you preform a factory reset of all DiGidot C4’s that you have connected. Disconnect the power, press and hold the button on the DiGidot C4 next to the outputs and power the device. Keep holding the button for 5 seconds.


What are the new features of this update?
Organize your DiGidot C4 devices into groups to control them for example: Group A plays Scene 1 and Group B plays Scene 2. Previous it pretty much was: Control one or all devices at a time.


Playing a scene is nice but now, a preset of scenes can be made, a playlist. Just like music, select different scenes, put them into a certain order, change the length of the scene, play random, etc.


Combined Triggers
First, every action was limited to 1 trigger (input source). Now it’s possible to add multiple various input sources to start one action. For example, when the onboard button is clicked and the button on analog input 1 is pressed, a red scene will be played.


DMX recorder
Record your DMX signal up to 2 universes.


The C4 is a very powerful device. But if you want to push it really hard, like having scenes with 8 or morge universes, you might want to know where’s the limit wiht the memory. We built a powerfull monitor where you can check the FPS of incoming Art-Net and scenes, the available RAM and the ping time of each connected C4. Extended variants will also write a log file to the microSD card to investigate if an error on the C4 is detected.


Quick Access
The Ethernet port of the C4 now features a DHCP server. For people which are not familiar with this: When you got the C4, just give it power, plug an ethernet cable directly from the C4 to your computer and browse to the website This DHCP server is fully automated and will not interference with other DHCP servers.


Scene Speed
Make the scene go faster of slower, even reverse is supported.


microSD Deploy
When you are preparing a large installation with only a slightly modified configuration for each device, you can use the microSD card to configure the device at boot. It’s possible to apply device, network and input/output settings.


Action List
Just like it’s now possible to have multiple input sources at 1 action, so is with 1 input source, multiple actions can be executed after the event.


Scene Editor
Recording with the C4 will be a joy forever: control the start/stop functionality with a Art-Net or DMX console. After the recording is done, you can trim the scene and adjust the effect before saving it.
Will my settings be transferred with this update?

The settings like the name and IP-address of the C4 will be transferred and the scenes will also be upgraded. But all the triggers will break so we suggest to backup your SD-card and after that, reconfigure your triggers.

Working with C4

Connection problem with the DiGidot C4

This problem can depend on multiple things. Below is a list of problems with solutions.

The computer netwerk card and DiGidot C4 are using the same ip address (most common)

When using the DiGidot C4 on a LAN you need to match the network settings. For example when your DiGidot C4 is configured to use the IP address “” and subnetmask “” your computers network needs to match that “10.x.x.x” range with subnetmask “”.


Avoid IP Address Conflicts

IPv4 address conflicts are a common cause of problems with DHCP. No two devices on the network can have the same unicast IP address. If a device is assigned the same unicast IPv4 address as another, one or both of the computers might become disconnected from the network.

When matching the static IP address to the settings of a local network you will need to make sure to give the DiGidot C4 a unused IP address to avoid IP address conflict. This may result in a unreachable devices on the network.


On Windows

Control Panel > Network and Sharing Center – Ethernet > Properties > Internet Protocol Version 4 (TCP/IPv4).
Then replace the IP settings in the following boxes to: IP address: Subnet mask:

On Mac

System Preferences > Network > Ethernet > Configure IPv4 > Manual.
Then replace the IP settings in the following boxes to: IP address: Subnet mask:
