I could really use three of these.
To be clear, the PBW board is an add-on to a DCSRC. You must supply a stock DCSRC base unit itself (handheld remote not needed). Once you modify the DCSRC to become a Perpetual Barking Watchdog, that becomes its sole purpose in life. It cannot be used to control DCS engines via the handheld remote.
So the configuration might look like:
The stock DCSRC on the left is what controls any DCS engines via the handheld remote. The modified DCSRC on the right barks the watchdog about once per second as long as there's power from the DPDT. As shown, if going this route you should put a piece of black tape over the PBW DCSRC's red sensor window so that any handheld remote commands do not cause the PBW to issue DCS signaling commands in competition with the left DCSRC.
Of course going this route means you can skip steps 1 and 3 in previous post. In other words, just turn sidings ON with the SPST and count on the PBW to issue a timely watchdog bark to keep a newly powered DCS engine silent in the shutdown mode. To each his own as to the value of this convenience.
