Sometimes you need to make a change in the programming of a Castle controller and you just don't happen to have a laptop in your man purse. What to do? There's always the old stick programming method that we all love to hate. Yes it works, but . . . there has to be a better way. Now there is Field Link!

Field Link allows you to modify the most commonly used settings in your Castle controller all at the touch of a single button. No computer needed (mostly). Simply connect the Field Link to the throttle lead of the controller and power the pair as described below. Click the button to scroll through and change the indicated settings. Can't get any easier!

But wait! Act now and we'll throw in Castle Link USB compatibility too! That's right, these cards are also Castle Links that give you access to the entire world of Castle tuning functionality.

Does it work without a computer or not?
Yes, mostly. The card is programmed to work with the latest controllers and software when it leaves the Castle workshop. It will work with all Castle Link compatible controllers running software released since 2007. Go to www.castlecreations.com for more details. There is always a chance that they will upgrade the controller firmware down the road and that upgrade may require that the Field Link be upgraded too. That is easily accomplished, but it will require a computer running the latest version of Castle Link that is always available for free on the Castle website. Castle will also be happy to upgrade it for you if you drop it in the mail to them.
