Now currently shipped with v2.105/2.106 firmware. and Uplink2.1

Beta firmware for the 2B is now available to our registered developers. Register now (it is free!!!) at https://www.e-stim.net

Our Digital Link Interface is a USB driven digital interface system designed to allow you to connect your 2B™ directly to your computer via USB. Various control programs such as Commander 3™ and E-Stim Connect will then allow control of your 2B via your PC or Mac , while UpLink2™ will allow you to update your 2B to the latest firmware.

Please note that UpLink2.1 is NOT available separately to this pack.

For general details and support details then visit at our 2B link support forum.


The Uplink2™ software is supplied as part of the Digital Link System and allows you to upgrade your 2B without having to send your unit back to us. In order to do this you need the link drivers (see below), the Digital Link System and the Uplink software. Once everything is up and running you can then download the latest firmware* and install via your PC or Mac.

UpLink2 software is supplied with the Digital Link Interface. It is not available separately. Uplink2 software updates are available if you return your uplink CD directly to us. Do not attempt to use older versions of UpLink They will NOT work with the new firmware files.

*Please note for technical reasons not all updates are available via Uplink, and there may be delays between updates being available via Uplink and our other Update services.

USB Digital Link

In order to use the 2B with the link cable you must ensure your 2B is running a minimum of software version 2.07. To update using UpLink you need to have the bootloader installed and be running a minimum of firmware version 2.104.

2B control units with older software versions many not have the additional hardware needed to work correctly with the link, and may need to be returned to E-Stim Systems for an upgrade BEFORE the link cable will work.

The USB Link is only designed to work with the 2B. It will not operate with any of our other current control units.

The Digital Link Interface contains all the additional electronics to connect the 2B to a PC or Mac with a spare USB connection.

Linux Users should find the USB driver is included in the kernel (assuming you are using 2.6.31 or above)

How to Install the Digital Link Interface (Windows 7 and above)

  1. Connect the Digital Link Interface cable to a spare USB port on your PC. Windows should detect the existence of the link cable, and then install the necessary drivers.
  2. If this does not work, and it may take a few minutes, then you need to install the drivers manually. Step one is to download the driver executable from https://e-stim.info/downloads/drivers . Further steps can be found in our detailed instructions on our Installing Digital Link Drivers on a PC page.

Should you need to manually install drivers for the Digital Link Interface then please visit https://e-stim.info/downloads/drivers where you will find downloads for the currently supported operating systems.

The Bootloader

The Bootloader is a small program sitting inside your 2B that is only used when you update the main firmware (the program that controls the 2B itself). Older versions of the 2B prior to 2.104 do not have a bootloader, so you need to install it first. Click for instructions on installing the Bootloader.

Version Released Notes

April 2013 The new bootloader Install before attempting an updated to 2.104

Installing the bootloader is fast, but it is critical. If you 'brick' you 2B and cannot provide the debug log file, or you have installed a beta that failed, then you will have to either purchase a replacement IC, or return your 2B to our workshops for an upgrade. Both the replacement IC and a workshop repair/upgrade are chargeable.

Firmware Upgrades

The firmware files are encrypted data files. Do NOT attempt to edit them as corrupted data files could potentially damage your 2B and will invalidate your lifetime warranty. To download, right click on the download link below and 'Save Target As' to your computer. Click for further instructions on how to install the Firmware.

Beta Versions of our firmware are available from https://www.e-stim.net

I have happily been using the Digital Link between my 2B and Mac for a while now but the other day I updated to the latest version of Commander and got a friend of mine in Germany to download it too. I was amazed at how easy it was to connect his copy of the software to mine and control my box remotely, which was AMAZING fun. Can thoroughly recommend the 2B and the Digital Link is well worth the investment too as it adds a whole new dimension to the play
