Signal Animator/2 version "CC" (use with external detector)
Signal Animator/2 using an external detector (NOT included). This version ("CC") is for use with 3-light or position light LED-based signals wired with a common cathode (negative). Has a "random mode" capability which, when turned on, will cycle through the signal aspects at random times with random durations. This can simulate "phantom" train traffic.
