I have been in contact with a few guys at Intelight and last week they were in town so we grabbed dinner and they got to come see my signals, including my own Intelight ESB. Much discussion, learned some of their upcoming products (sorry I was asked to keep it to myself). But it was a great time to connect with them. One guy was VP of engineering, and the other was a software developer for the ESB and their controllers.
I don't know how these were programed, just happened to see them in used and stopped to check them out. The controller cabinet is an Econolite NEMA "P" type.
