As you can see this opens up a new world of possibilities...

This is great news indeed, thank you for posting.

Has anyone tried the rc train remote on a power function reciver to see if it uses the single output pwm control signals? If not, hopefully the new RC train system will be compatible.

It also looks like with the right signals, and a bit of tweeking of the wiring, you could control a train motor speed and direction on one port, as well as two 0v/9v outputs on another. I didn’t see a way in the document to turn bothe control lines to 9v, but they can bothe or individually be set to 0v!

Does anyone know how much current the control lines can supply/sink?

(...) Either single pin modes allow to set each output to 1 (9V) or 0 (0V). (...) See the drive datasheet: (URL) can reach 1A peak, continuous value is lower (500-600mA) especially if both outputs are heavily loaded at the same time.

(...) I'd be very interested in that experiment (using a Hobby train RC on the PW Receiver) as well, but this does answer a number of questions for trains. For instance, tunnels and large layout out of line-of-sight on the RC should now be possible. (...) (16 years ago, 26-Jan-08, to lugnet.technic, lugnet.trains, lugnet.robotics)
