The SJ Research BEN looks very similar to the SJ Econet Bridge but instead of bridging two Econets, it acts as a bridge between an Econet network and a Nexus network. As such it is a very unusual piece of kit and has a rather limited application, but I've got one and you can see learn all about it here by clicking on the picture links above.

In addition to 27 images of the BEN in this picture set, there are two short video clips showing the start-up and test routines of the unit. Although the clips are fairly low quality, I have put these clips here as they show the BEN in operation in a way I could not capture in still images.
