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. It is supplied with a USB Memory Stick containing instructions on how to install the Digital Link Interface Cable along with various drivers and copies of our various control programs such as Commander 3™ and E-Stim Connect which will then allow the 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 & 2.3 are NOT available separately to this pack.

For general details on how to use these programs then visit the relevant links above, where you will also find helpful instructions on how to install them and some troubleshooting guides. You may also wish to join our Forum.


The Uplink2.1 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. Uplink to Uplink2 software updates are available if you contact our Customer Service at . 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 Link Drivers

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.

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

How to Install the Digital Link Interface (Mac OSX)

Linux Users should find the USB driver is included in the kernel (assuming you are using 2.6.31 or above). Please note that although we supply notes for Linux, we don't currently offer support on Linux.


Should you need to manually install drivers for the Digital Link Interface then please visit where you will find downloads for the currently supported operating systems.


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 firmware version 2.104 do not have a bootloader, so you need to install it first. Click for instructions on installing the Bootloader.

Installing the bootloader is fast, but it is critical. If you 'brick' your 2B and cannot provide the debug log file, or you have installed a beta that failed, then you will have to return your 2B to our workshops for a Workshop Upgrade.

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 Guarantee. Click for further instructions on how to install the Firmware.

Beta Versions of our Firmware are available from publicly released version of Firmware are available from our Firmware Downloads Page

Version 2.07 is the minimum Firmware required to operate the 2B Digital Link Interface System. Should you have a 2B with version 2.06 or below, then you will need to return your unit for a Workshop Upgrade. Version 2.09 is the minimum required to operate with Commander™. 2.104 has the Bootloader installed, but if you are upgrading from an older release the you will need to install the Bootloader first.

You do NOT need to install older firmware updates, the latest firmware version will have all the options and bug fixes of earlier releases.

Please note BETA files (marked with a 'B' in the version) have not yet been fully tested, and may have bugs. If you find any please report them on our Forum. Before attempting to download and install BETA files, you must ensure that you are running the latest version of UpLink, and have the latest Bootloader installed.

I purchased this cable and USB interface. No problems installing the software but I have not used the programming. I also installed the Commander3 program. The Commander3 only allows you to control the estim programs on the 2B. The sharing program is also just for the 2B files and I don’t know anyone personally that uses a 2B. But it works as advertised.

I didn't notice any changes in the menus with the upgrade. I expected at least a couple of new settings and double the output voltage as I read in the upgrade notes, but I noticed nothing. Although I followed all of the steps and got all of the expected responses, I don't know if there is anything different after upgrading. Admin: Without knowing which version you upgraded from and to we are not able to comment, but in general the updates have been bug fixes. A firmware update will not be able to increase the output voltage beyond the capabilities of the hardware. I am sorry if you are disappointed in the upgrade.

This is a five star item to use with a computer. Using it with the installed Commander gives easier control over the 2B unit. There are two things that I'd like to see: 1.) The ability of using the sound on the computer in the "Stereo" mode, and 2.) An app to do this with either an Android Tablet or an iPad.

This is an awesome product. It might even change your life. If you run into problems with it be sure to ask the staff or the user group for help. They are very accomodating, and of course knowledgable.

2B Digital Link System works great. Software download went well and Commander works great and has a lot of creative possibilities. Installation of the software was not straight forward. In my case I had to install 1) drivers on my computer; 2) boot loader; 3) new version of 2b software. This was not really clear in the instructions on the flash drive so software upgrade took at least twice as long as it need to take. [ED:Software installs are slightly more complex with older version of software (prior to 2.104), but we are reviewing the instructions.]
