FS MTH DCS TIU ver 6.10 - DELETE please

MR_P ·
Have an extra TIU, just updated the version to 6.10 and used it today, to make sure it works fine. The model is rev I or L, not sure see pics. I'll include the USB to serial cable that you need if you want to hook up to a WIU or update it later. $125 and I'll cover the shipping costs within the lower 48 states. Contact via email in my profile please. ase.

Engine does not work

lehighline ·
This is an MTH Railking Mohawk, 30-1166-1. I put a BCR in it a while ago. The headlight kept burning out, so I replaced it with an led. Otherwise the engine is stock. I went to run it recently and found out it would not work. It does not add to the remote, and if I take the TIU out of the mix, it won’t run in conventional. I’m using a 3ft section of Gargraves as a test track. I was able to add a “known good” engine to the remote, so I know the test system works. Suggestions please! Chris LVHR

Howdy Friends! Here's one that has me puzzled. I have an MTH-Ives 3245R Loco Product # 10-1218-1 (3 volt board) that runs normally in DCS for about 30 minutes then cannot be controlled by hand held remote. It maintains set speed and all and when but when I hit the "read button" it says "Engine not on track" ... Shutting off the power and waiting a minute and powering up again I can regain control. Does my loco have early onset Alzheimer's or what? I have track signal of 10's, TIU and Remote...

TIU and remote programming

rrman ·
Sure this has been asked before I was contemplating this summer (layout down time) having my TIU and remotes updated to whatever the latest greatest rev is assuming it is bug free . I know, do it yourself but the last time took two days of frustration ( and blue language) to get to ver 4.02 (or 4.2 can't remember which) years ago . So is best bet shipping back to MTH or someone who has the setup (mine is old RS232 plug) that zip-zip and done and knows all the work arounds of upload/download...

Star Wiring for Around the Room Shelf Layout DCS

I have build an around the room shelf layout, its roughly 12'x12' and no more than 2' deep benchwork. I suck at electrical, and Im trying to understand how to wire for DCS.

Hi all, I have been having some issues with my DCS system lately. I have a DCS/Legacy hybrid system where my TIU is connected to my Legacy base so I can run TMCC locomotives from the DCS handheld and TMCC/Legacy locomotives from the Legacy handheld. An issue that I have always had and cannot figure out the solution to is why there is always a problem with starting up a locomotive if it is on the same track as a TMCC/legacy locomotive.

My Run Room is 23' x 69' with an L shaped area for running. My website gives a lot of information that applies to large DCS layouts. You will probably be happiest with your TIUs centrally located. See my track with the Self Guided Photo Tour . My 4 TIUs are centrally located under tables on control carts. With really good batteries in the remotes I almost always have train control. When the trains don't see the remote they continue running per last instructions. Once trains are entered into...

Re: DCS TIU & AIU on large layout

MI-Marc: My personal recommendation would be to keep the TIUs above the table. (They could be disguised in buildings if you short the fuses and use external breakers or fuses, reducing the need to access them). Anything, be it concrete wall , wood, etc., may diminish the remote-TIU signal, however slightly. Under no circumstances let metal, like chickenwire, come between them. Also, do not stack the TIUs, or have anything metal near them. The above suggestions are based on my experience on...

24VAC Z-750 Brick - where to use

I have an older brick for the Z-750 that is 24VAC. I've read that this voltage is too high even for MTH engines. I was going to use it on my test track, but now I'm not sure where to use it. Can I use it to power a TIU Rev L without hurting the TIU? Maybe LED lighting? Any guidance would be great. Thanks.

Re: MTH REAL TRAX ELECTRICAL GREMLIN

Welcome aboard Stan. It seem you guys are trying to make blocks by insulating the outside rails, It would be much easier to leave all the outside rails connected together and use the toggles to turn the different blocks on or off Via the center rail hot. . Yes you would need 4 center rail insulated joints, (2 on each switch) and 2 outside rail insulated joints for the non-derailing feature on each switch. Don't forget your freight cars are like jumper wires jumpering the outside insulated...

Hi Gregg.... Thanks so very much for the quick response. Yes, to isolate the center rail could be an option. We looked at the manual for the O31 turnouts and MTH recommends isolating the rails the way we did. The problem is with the joint at the turnout at the green arrow. The inner "siding" isolates just like the way the diagram on page 14 of the manual shows... Everything else is isolated. We did flip flop the SPST toggles and had the same results. And yes, again, we are aware that the...

Re: MTH REAL TRAX ELECTRICAL GREMLIN

Yes you can still keep the non-derailing feature if you use toggles to turn off center rail power... I don't understand what MTH is describing, but I doubt it's about creating blocks by insulating the outside rails... I think you're making it much harder than it should be. Switch the hot. One SPDT toggle to select TIU or Z-1000 conventional... I'd probably use a center off type as well. 3 on\off type toggles for the 3 blocks.

Stan, If you have continuity at the green arrows the ends of the rails are most likely touching. Try taking the track apart and putting a small piece if electrical tape on both the outside rail ends you want to isolate and re assemble. Galon Tonell

Stan, How are you connecting the power feeds from the TIU to the track? RealTrax Lock-on? RealTrax is designed so that the Lock-on determines which outside rail is the Common(neutral return of AC) by it's orientation. The plan on page 14 has the lock-ons oriented to the outermost rail being the common for sidings and isolated part of the loop and the main part of the loop has the innermost outside rail connected. The outermost outside rails are isolated just past the thru and turnout of the...

I have never heard of breaking outside rails to create blocks, and I'm sure you're misreading MTH. It isn't practical because trains will be jumping the gap for long periods of time.

Re: MTH REAL TRAX ELECTRICAL GREMLIN

The pic from Moonman (MTH) shows the non - derailing feature for one route only . The insulated pins are definitely shown in the wrong location for non-derailing on r the other route. At one time I owned a Real Tra x switch and believe it also has center rail power routing... Could be mistaken on that one..

It's a control block to disable a train. The longest train to fit is the length of the track between the switches. A & B. It doesn't matter which side of the circuit that you interrupt. Only one outside rail is active. It's an MTH wiring diagram. See that page in the above post. That's what they are following.

It's not a block, but an isolation track to park a train with no power. It does not matter which side of the circuit that you interrupt. messing with the center rail on this DCS track plan could mess with the DCS signal. yes, there different ways to do this, but they are following the plan from the MTH manual

messing with the center rail on this DCS track plan could mess with the DCS signal. Since I do it on some70+/- toggled blocks, I can assure you it doesn't. It does not matter which side of the circuit that you interrupt . Suit yourself. I'm with Gregg. The 99-44/100% practice is the way to go If outside rails are unpowered, you'll get surges as cars with varying degrees of conductivity go over the gap. Then when the PS2 or PS3 board gets damaged, MTH will be blamed for poor quality. To quote...

[ Hi Stan, Hi Joe... the manual for the REAL TRAX 031 switch. The diagram on page 14 ..] I now see what you are referring to. I see this would work in conventional, but in DCS the engines will startup in conventional because of the watchdog signal being present only for 5 seconds after the TIU channel receiving power. Of course you can either repower the channel, press the start up button or use Barry's trick to make the engine come up silent. Learn something everyday.
