NO! You will only cause problems connecting TIU outputs, that's a giant no-no!

Can you elaborate on this? What is it about hooking two TIU outputs together is a no-no?

For example, would powering the donor TIU channel with a separate power supply and then capacitively coupling the two channels help so that "only" the high-frequency DCS Watchdog signal is injected into the yard track?

Does this apply if the TIU output is from a completely separate TIU? That is, someone may have an old version or partially functional TIU and use it as a Watchdog generator. On eBay now the cheapest you can get a USED DCS-RC is $130 plus shipping. New ones go for $200 and up! At those prices kind of begs the question, why not or what would it take to apply an unused TIU channel?! confused
