@DdotCdot posted:John - I've never seen the DCS Remote Commanders set up like this. In what way are they repurposed here? / What benefit are they providing via passive-configuration in conjunction with TIU channel outputs?
The DCS-RC boxes are watchdog generators, they have my Watchdog Reset Board in them to generate continuious WD signals on the TIU channels. Each box generates a DCS WD signal once a second for it's respective channel.
