Nope, other than cycling power on the input of the TIU channels. I obviously have the full TIU, but I also have three of the four channels being fed by my WD generator. This allows me to switch individual sidings that are powered by these channels and not have to turn off the entire channel to insure a WD signal to keep the engines silent.
DCS-RC boxes at the top are all equipped with the WD board and service everything but the mainline TIU channel.
