Wires are wires. If they aren't damaged and their spec's are within the needs of a different timing system, they will work just as well as they would with Compulink's computer and sensors.
Coke or Pepsi? Dr. Pepper or a scotch and water works too.
Wires are not wires. For the past several years, Compulink has been working to change tracks over to fiber-optic. Different systems use different sensors, different wiring configurations, and different computer equipment. Do we know that the wiring in place at the track is fiber-optic and that it meets Compulink's specs? Do we know that it has been installed correctly and configured the way Compulink installs it?
I worked with Compulink, Portatree, Accutime, and one other system I do not remember the name for. They all worked fine on their own but they are not plug-and-play interchangeable.
I am sure Bob would like to have every track in the country use Compulink but that is not what his position on this is about. Rather, he is saying that he and Compulink will not be responsible for problems with the system if he cannot control every part of the system. If you are going to use the Coke or Pepsi analogy, keep in mind that Coke is very strict about restaurants not being allowed to serve Pepsi if their signs or menus say Coke.
You wouldn't put a Chevy engine in a Mustang and expect Ford to take responsibility for it if the engine does not work, would you?
