George Mason posted:The top one is the FRM01 that I started all this with. I was able to get one of the NE555 boards to turn on power to the siding and simultaneously activate the DSC signal. But, it created other problems that I haven’t tracked down. The bottom line is that the NE555 board remains powered on until I turn off the siding. Which isn’t a bad thing.
When you say "remains powered on" do you mean the RELAY on the board remains powered on? When a new siding turns on, the RELAY on the NE555 board should only turn on for a few seconds and then click off and remain off even if the NE555 board itself remains powered on. This is critical to the operation of this method. The DCSRC must turn on for only a few seconds when any new siding is powered up. The DCSRC must then turn off until another siding is powered on. This is because the DCSRC only generates the magic watchdog signal when it initially received power.
And of course the above only applies to the current method under discussion which uses a "stock" unmodified DCSRC. If using the modified DCSRC (a.k.a. Perpetual Barking Watchdog) or a FRM01-like timer programmed to continuously cycle power on and off to a stock DCSRC, you do not need to mess with the Delay-OFF timer relay modules.
