I recently had to do something similar. We deal with multiple pieces of the same type of hardware, just ones made by different manufacturers. The key point that I realized was that: It does NOT matter what hardware we're sending to - our program can send a command to the hardware without having any idea what it's sending. And that's where the ICommand pattern came in handy. In fact, it turns out that for most hardware, we really only have about four commands. The reason it's this way is most of the hardware we have to deal with will only send a key value pair into the hardware, and get a key value pair out. Hence, I just have the UI be responsible for sending the correct values for the command (which it gets from the user), stow them in XML, and send it off to a simple command factory in order to build the correct command type based on the XML.
