I just purchased a new Rev.L TIU, and I'm new to DCS so bear with me. I have my KW transformer wired to Variable IN1, and when I power up the transformer the red LED doesn't blink, flash, or turn on. I removed the TIU cover and verified that the fuse was intact. I also verified that I have 18 volts to the terminals. When I try to connect the DCS remote it says "TIU address 1 not found". Does anyone have any suggestions? I did a forum search but didn't see anything. Thanks in advance.

If memory serves, you need to connect transformer power to Fixed 1 in. If you want to vary your voltage w/ DCS, then jumper over to Variable 1 in, and connect your track to variable 1 Out. Most of us by-pass this minor headache and use a small, power supply that plugs directly into a wall recepticle (wall wort). The other end connects to Aux Power. AC or DC will work, 12-20v. Radio Shack sells them.

 

BTW, if you want to vary your voltage, you need to set up variable1 (or 2) in the handheld first. I strongly suggest you get and read Barry's book, The DCS Companion. He covers this (and a whole lot more)!

"I also found that I had to have the track connected to Fixed 1 in order to 'find' my engine."

 

This is EXACTLY what happens if you do not have Variable 1 set up! There is no voltage to the track, so no power to the engine, and no DCS signal back to the TIU. Put a volt meter on the rails (center to either outside rail) and you will see what  I mean. So setup Vari 1 in the handheld, then TR, select the name you gave it, and dial up the voltage on the hand held. Don't forget to feed voltage to Vari 1 from the transformer! Set it for 18v or so.

 LOL

 

May I say that I think that Barry's book is a necessity for any serious DCS operator.

He is always candid and helpful on the forum and his book really "nails it." It is answers based on experience.The DCS COMPANION is just as important as the transformer, TIU and Remote for operating DCS equipped MTH trains.

Personally, I learn something every time I log on to the forum or read the book.

 

Cordially,
