(...) it on a scope. If we have a PWM voltage with a 50% duty cycle and 10 millisecond period An analog voltmeter will report the average voltage of 4.5, not 5 milliseconds DC 9V and 5 milliseconds DC 0V because it does not have the timescale (...) (26 years ago, 8-Mar-99, to lugnet.trains)

Since I released Track Designer 2.0 I've had a number of people email me saying that after they install it says it can't find the registry.tdl file. Why is this? I've never got to the bottom of it and despite requests no one has ever told me if (...) (26 years ago, 8-Mar-99, to lugnet.trains)

(...) I'm not sure I agree that the voltage is variable. People have reported (via oscilloscope analysis) that it's pulse width modulated 9V instead. This will read on an analog meter like a low voltage, because it's taking the average across time. (...) (26 years ago, 8-Mar-99, to lugnet.trains)

How have you got this working? I sat down and had a long think about it last night, and played checked out my points with a multimeter to see which circuits get broken when you move the points, and I can see that you need to cut the rail on both (...) (26 years ago, 8-Mar-99, to lugnet.trains)
