Category: Commander

If you are running Windows 10 then you should not need to be following this process as Windows 10 should have picked up the current drivers for the Digital Link Interface, but if for any reason they did not install automatically then you will need to follow these simple instructions.

Before Starting

  1. You will also need Admin access rights as you will be installing drivers.
  2. You will need a spare USB port on your computer. It is normally possible to install the Digital Interface via a USB socket on a USB hub, but it is not recommended.
  3. You will need the E-Stim Systems Branded USB Stick that came with your Digital Link Interface or internet access to download the latest drivers.

You will find the drivers either on the USB stick supplied with your Digital Link Interface or they can be downloaded from the Download page . Depending on where you have obtained the driver follow the relevant version of the instructions below.


Installation From USB Stick

Plug the USB stick supplied with your Digital Link Interface into a spare USB port on your computer, navigate to the USB stick directory and then open the folder called ‘Drivers’. Inside this folder you will find a file called ‘CDM21228_Setup.exe’ double click on this file.


Installation From Download

The downloaded file will be a Zip file called ‘ You will need to extract this zip file to your desktop. Once extracted navigate to the extracted folder and open it. You will find a file called ‘CDM21228_Setup.exe’ double click on this file.

You will now need to agree to the Licence Agreement by selecting ‘I accept this agreement’ and click ‘Next’. The drivers should then start installing and when complete you will see this screen.




Now click 'Finish' and window will close and the drivers are now installed. You can now remove the USB stick from your computer if you were installing the drivers from it.


Checking The Drivers Installed

Tip:- If you do not know how to find the Device Manager on your Computer then you can use the Windows Command ‘devmgmt.msc’ If you hold down the WIN key + R you will get this dialogue box come up on the screen:



Type 'devmgmt.msc' into the box and click 'OK'. This will then display the Device Manager for you.



If you don't see the Digital Interface, or if you don't see 'Ports (COM & LTP)' in the list, then either the cable is not correctly connected to your PC, or the drivers have not installed correctly.
