Firmware Updater

Use the Firmware Updater Application to install the latest software version to your controller.

Firmware Updater on Mac

The Firmware Updater Application is available for Mac and PC and is currently in a beta version. The purpose of the application is to make it easier to upgrade your controller to the latest firmware. For UniSketch based controllers the firmware can simply be updated by pressing "Check for updates". Please notice that any local settings you have on your controller will be overwritten with the controller setup you find by pressing the "Open Configuration" button. This will direct you to your very own controller configuration page on

For uploading a new firmware, you need to connect your controller to your mac/pc with the programming cable (USB cable).


Please Notice: Using the "Check for updates" will only work on UniSketch based controllers. Do not attempt to upgrade non UniSketch based controllers as this will interfere with the firmware on your device.

First download and install the FTDI/VCP driver.

Then download and install the Firmware Updater application:

Mac Version V2.1
(For Mac OS X El Capitan or newer)

PC Version V2.1
(Tested on Windows 10)

Connect your controller with the USB programming cable and press "Online Configuration" to enter the configuration page on for your particular controller.
Edit, modify and tweak your config and press save.
Press "Check for updates" to update the firmware on your controller.

Identify Microprocessor in Your Controller.

Please notice. The below .hex firmware files are for non UniSketch based controllers only. In order to download the right .hex file you first need to identify the microprocessor in your controller. Use the picture as a reference, and see your invoice for MCU details. The Firmware Updater Application only works with EtherMega, SKAARDUINO and SKAARDUINO Due based controllers.

The serial monitor is a great tool for analysing your controller. The tool can be used to check current IP settings, and to determine any network connection issues. If you experience any connectivity problems, we recommend connecting your controller directly to your ATEM switcher to confirm the controller can communicate with the ATEM Switcher and IP settings are correct. 

In order to use the serial monitor you need to connect your controller to your mac/pc with the programming cable (USB cable). 


In the UniSketch manual you can learn about the different commands you can send to your controller via the Serial Monitor.
