So several years ago I got a crossbuck controller from TMIDigital. It used optical sensors to activate crossbuck LEDs. I am trying to find the instruction manual for this product, but I am not having luck. Seems like they were active on Twitter in summer 2010, and that's it. Their website, tmidigital.com, does not work any more. If anyone purchased one of their items, specifically the grade crossing controller, do you have a copy of the instruction or wiring diagram? Also, the LEDs on the crossbucks are blinking when the optical sensors are not installed. Why are they doing this? They should only be activated when the optical sensors detect a shadow.
