Barry,
I can understand how you are set up, however you should be able to use the Z4K normally to initiate power and run your DCS controlled trains. This is why I have always believed this is a P3 engine problem, especially when the old ZW, left with the handles up, would operate the P3 engines properly, from the DCS hand held remote control, the P3 engines in both the TR modes, and the engine P3 mode. Now he is saying the same thing, but instead of using an old ZW with the handles left up to 16-18 Volts, they are using modern bricks, as the power supply. The P3 engine is the common factor, in the problem, and not all P3 engines have the problem.
