Curiosity got the better of me so I extracted the CH1 trigger input circuit of the FRM01. Here's one way to take advantage of CH1 and the FRM01 Function 02 so that a single FRM01 can handle multiple sidings using an unmodified (stock) DCS Remote Commander to supply the watchdog signal.
Following each 1N4003 diode, insert 3 cents of parts (a 1M resistor and a 1uF capacitor) as shown. To be clear, I do not recommend this since it means messing with loose components and soldering.
I present this for the record as I can imagine other AIU applications where multiple ACC(essory) ports can trigger a single FRM01 to perform some kind of timing/delay function for layout accessories.

Right now, I have it working. The constant clicking gets a bit old, but at least it’s functioning. I may try another set up with this design and see how I like it. What do you recommend as a board to build these on? Is there a perforated soldering medium to build it on?
