Just getting into this DCS thing, because eventually I'd like to control all my engines via 1 setup. I've only got 2 DCS capable locomotives (soon to be 3 after I upgrade my Blue Comet Pacific to PS3). I've got several TMCC and several conventional locomotives. No room for a layout currently, but I have a test track running the length of a buffet. Had it powered by a Lionel PH-1, with a Powermaster connected so I could control conventional locomotives via a Cab-1 remote. That recently started acting funky (replaced the remote's batteries, but it's still not sending commands correctly), so since I had a couple of TIUs and a DCS remote awaiting future expansion, figured I'd hook that up.
The TIU works great with my 2 DCS engines. However, when I switch the input and outputs to Variable 1, I'm getting nothing. I have a jumper on the red terminals from Variable in 1 to Fixed in 1 in an attempt to power the TIU. Is a jumper needed on the black terminals too? Just looked at the DCS manual in a PDF file, it clearly shows a wire between the red terminals, and it looks like someone drew a line with a sharpie between the black ones. Hadn't noticed that before, and figured the commons would be connected together. Figured I'd ask here first before I blew anything up.
