I received the TIU and WIU in the mail. Purchased the Premium App, have a Lionel 180 watt connected to tiu with the banana plug style the goes into the molex into the Input fixed 1.
then track connected to output fixed Dcs 1.
Lionel 990 is plugged in power and have the vga or whatever it’s called connected to the vga in TIU.
Don’t know what kind of connector to use or where to put the U from 990 to the TIU?
I think that’s why it won’t work. I can connect Mth engine no problem.

Robert,
Lionel 990 is plugged in power and have the vga or whatever it’s called connected to the vga in TIU.
That's one problem. Due to Lionel's design of the Legacy Command Base's serial port, when connecting the TIU directly to the Legacy base, you can only operate Legacy engines as 9f they were TMCC engines. The Legacy base will to accept Legacy commands via its own serial port.
In order to have Legacy engines defined and operating as Legacy engines using the DCS App, you must have the TIU's serial port connected to a Lionel SER2 module. How too do this is addressed, in detail, in The DCS WiFi Companion 2nd Edition.

If by the "U", you mean The "one wire" that connects to a screw lug on the Legacy Base, although there are a couple places that the wire can be connected, the simplest connection is directly to an outside rail. Just be sure not to connect it to a TIU channel input.

Ok retrying I had the vga goofed like u said.
Moved the legacy U attachment with a black cord to the outside rail.
Does the legacy need to be turned on or the remote removed from the base?
Dont know where that port your talking about would be on the TIU to enable legacy.
Just tried again with the sw7 with no luck.
Robert,
You must connect the serial ports on the TIU and Legacy base using MTH cable #50-1032.
Legacy Cab-2 is not used when operating TMCC or Legacy engines with the DCS App.
It’s all in my book - read it!

So I need the ser to get the legacy part on the dcs.
Im going to buy your book for sure.
Thanks Barry
Robert,

That's an older version of the diagrams for use with the 1st edition of the WiFi book. It was updated and included in the 2nd edition. That file now serves as a "teaser" for the 2nd edition.
So I need the ser2 to get the legacy part on the dcs.
Yes, that's correct. You'll also need a cable, as described in the book.
I'm going to buy your book for sure.
It's about time! 
The cable i have is the 1032
Robert,
The cable i have is the 1032
That's the correct cable.
Robert,
Not sure if I’m buying the Ser2 and Db9 for another $80.00. I’m weighing the options.
$80 will buy both of my books in the print editions with a few bucks left over!
What are the benefits of having the LCs Wi-Fi vs not and just the ser2? Do you lose any features or will they be exactly the same?
I’m going to test my Acela with the Dcs App tomorrow. I know it’s just Tmcc but I’m not sure if I really trust the app controlling it without the preciseness of the legacy remote .
Does the Legacy version of the app have a more precise speed control gauge like the Mth engine I have has on the App?
Robert,

The only benefit the LCS module itself really provides is to allow you to use Lionel's iCab and LCS apps.
The LCS App, while free, does far less for train operation than the Cab-2 remote, although it does allow you to use Lionel's wireless modules to construct a visual track plan on an iPad and throw switches using the iPad.
The iCab app, for a $50 price tag, pretty much allows you to do most everything the Cab-2 remote allows. However, you can do about 98% (approximately) of the iCab's train control from the DCS App if the TIU is connected to the SER2.
Does the Legacy version of the app have a more precise speed control gauge like the Mth engine I have has on the App?
The iCab app has, I believe, a speed control mechanism that's similar to that of the Cab-2 remote.
Regardless, I'm hardly an expert regarding Lionel's LC'S app's capabilities. Possibly someone more knowledgeable than I of the two Lionel apps can add to, or correct, my statements.
Got the ser2 and db9! I figured I'd rather try it all together. If I dislike it I want to keep them separate and get a
Robert,
Why do you want a 6-34120 TMCC Lockon?
A random reply so I can find this later. Getting tired of waiting for Lionel to make an Android app.
Dont I need the Lock-on to utilize the 180 powermaster to my legacy 990?
Robert,
What are you trying to do, exactly?
Or can i plug the 180 into my 80 watt transformer with the banana plugs coming from the molex.
To beef up the track power for my Acela to run on my big o-72 loops.
The Acela will run quite well with the 180 brick. I used it for my layout when I had the Acela. The Acela was just TMCC (I think) and make sure that you have a 21 inch or longer straight section between all of your O72 curve track because the tilt mechanism will mess you up if you do not have straight sections at least the length of a coach.
Winrose how did u hook the 180 to your track? Or legacy 990?
Barry off topic. Received this in mail today pretty busted up for a brand new train with the rear pantograph not fully functioning.
Robert,
Exactly what is wrong with the engine? If it's in the pictures, I'm just not seeing it.
Pantographs don’t operate and it’s damaged.
Also the front pantograph is bent
Barry when you look at photos it is written in small print after some numbers at the bottom of the pic. When you read it and look at pics it is very obvious what the damage is. I too did not see it at first.
They’re sending me a return label for it and a replacement.
Robert,
OK, now I see.
I would have sent a video but I need my phone to run the thing at the same time.
Barry I got the Lionel Legacy engine to work on the app but I still can’t link the Acela. Any idea?
Afraid not...
Really how come I thought Tmcc would work?
Robert,
Both TMCC and Legacy work just fine using the DCS App. I run both on my layout using the app.
You haven't provided any real indication of what you do with the app, how it responds or how you have your DC S and Legacy connected. The 3 pictures don't provide much in the way of any real information. Until you can provide an accurate description of these three pieces of information, it will be very difficult for anyone to assist you.
So I have a it setup exactly like the diagram you made with just the Ser2 and Db9 cable, no Wi-Fi though.
Power
lionel 180 to molex to input 1 tiu
output tiu to fastrack
wiu to tiu
wiu to power
legacy 990 to power and one line to track and then to Db9 to Ser2
Ser2 to the tiu with the 50-1032 cable mth
Barry,
I did all you described and my new Legacy SW7 ran just fine on the app. I love the wi-fi. Easy.
John
Robert,
So, exactly what are you doing to try to get the Acela to run and exactly what happens?
It wont link. I tried to add in the APP to the Tmcc /diesel and tmcc/steam and legacy/diesel and legacy/steam but still wont go. I make sure the TIU is found and it is.
Robert,
Details, please! Exactly what did you do and exactly what was the app's response?
Also, what was the position of the engine's RUN/PROG switch?
Barry you have the patience of a Saint!
Ill tape it tomorrow and will go slow so you see it and can probably pick it out right away.
Thank you again.
Robert,
What was the position of the engine's RUN/PROG switch?
