it seems that both Barry's method, and the method involving using the DCS RC have their pros and cons.
Using the DCS-RC is a more fail-safe method. But you would need to have one connected to each of the sidings (or am i not thinking correctly).
Barry's method (which I wasn't aware of before reading this post, so thanks Barry for yet another piece of DCS wisdom) doesn't require extra purchases, but does require some good diligence to ensure that the remote is ready and set before powering up the siding.
