MTH Proto1 question

Proto 1 isn't command--think of it as just conventional with sound and a few other features accessed by combinations of horn and whistle commands on half-second intervals. Your Z4000 can issue those commands for you if you can't get the timing down (assuming you even need to tinker with them)

Proto Two (and three for that matter) is command--but it will happily run in conventional as long as you like--you just won't have access to some of it's more advanced features without the DCS system.

With any of the above, smoke-equipped units will have a switch to turn the smoke unit on/off.

David, the Z4000 was originally designed for Protosound 1 locomotives, and will have no compatibility issues with it.  It is the easiest way to program Proto1 features. Regarding smoke, there should be a small switch on the locomotive that turns off the smoke unit.

The Z4000 can be controlled by a DCS remote using the Z4000 remote receiver accessory. With this setup, the output voltage is a variable amplitude full sine wave, not a chopped sine wave, so it is compatible with any locomotive.

David, Red Block has it right.  No problem with Z-4000, and the PS-1 is conventional with volume pot to control sound, and a switch for smoke.

Railride I think you are confusing PS-2 conventional ops with PS-1.  There are no 1/2 sec intervals with PS-1.  It is controlled via voltage setting, and use of the bell or whistle.  No combinations.   G
