The DAC20 accessory decoders all have very similar settings.
They are powered from a DC 24v supply, rather than from track power. This means they would get commands even if there were a DCC short. (It also means they can't participate in DCS100 command station routes, but I don't use those). So the 24v power is connected to SK1 pins 1&2; and the boards have a ground wire connected to the command station ground. The "use LocoNet commands" option is ticked in locoanalyse.
For SEEP point motors, the default output timing is used. That means each output is active for 0.5s, and there is a 0.8s delay between outputs programmed for the capacitor discharge unit. That means if several points are changed at the same time, the DAC20 will space them apart to make sure the CDU recharges.
There is an option in Traincontroller to put a delay on each junction when points are changed, before it will drive a trian through. I think that is set at 1 second, which seems to be long enough to allow 2-3 points to be changed.
