OK, David, but did you have to physically modify the variable outputs to switch them to fixed, did you just use the command from the remote control, or are you running the fixed voltage transformers through the variable output without making any changes to the TIU?
I'm asking this because, as one of the San Diego 3 Railers dealing with the DCS mess on the layout, the explanation I'm getting for them not switching out the ancient TIU to see if it may be defective is that the variable channels have to be modified to run as fixed only before they can use it. Since they're running the TIU with a passive connection now, the issue of whether a channel is fixed or variable seems to be moot point.
