Connecting Command Base To TIU

Spence,

Does this mean the variable outputs as well as the fixed outputs??

Yes, that's correct.

Thank you I will try it on Monday. I just recently got into MTH PS-3 & love the engines. I was always a Lionel man but I'm starting to rethink that.

Well I hooked up the jumper wires to all 4 output channels & ran a wire from the #1 fixed outyput to the command base which is the fixed one that I'm using but it dosen't reconize any PS3 engines. Did I hook something up wrong. All my connections were tightened.

Does DCS find your MTH engines with the TMCC base disconnected?It may be time to check out the signal strength on each tiu  channel with a small test track and one engine. Should get a perfect 10.

Yes I have no problems with the TMCC disconnected.

I know this may sound like a silly question but if the TMCC base is connected you must have TMCC engines, There are some TMCC engines that will degrade the dcs signal big time. Enough to really mess up DCS. Which ones?? it's kind of a try'em  to find which ones   by taking them off the track one at a time.

If just connecting the command base messes things up without any tmcc engines on the track,  well I  don't know. The only thing I can think of is... An out of phase power supply  where all   the commons are all tied together via the black tiu outputs.  Not likely. Do you have completely  separate loops with different power suppies?

I haven't got to the TMCC engines yet. The remote won't reconize any PS3 engines.

I was curious based on the original wording of the first post what you were trying to get to work.  (I was unsure if you were saying the TIU would not recognize PS3 engines, which is what people were trying to help withup until now, or if you meant the TMCC remote would not recognize PS3 engines)

It seems from the last reply you are trying to get the TMCC remote to recognize the DCS engines.  That will never happen.  The DCS remote can send TMCC commands to the TMCC (or Legacy) base via the serial port interconnect cable, but the TMCC base cannot send DCS commands to the TIU (via the cable, or in any other manner).

When I hooked the jumper wires the remote was unable to read any MTH Engines or run the TMCC

Jumper wires  There should only be a single wire from the Legacy base to the outside rail.

This is not Legacy; Cab 1

Same answer.   You don't need the serial connection to the TIU for TMCC to function with the CAB1, get that running first.

Are we talking about jumpering  the black TIU out-puts ?

We're going to need a little more info.

How many TIU channels are you using and how is each one powered?

Why not try hooking up just one tiu channel say fixed 1  and hook  the U connection

to it, disconnect the jumpers to the other blacks if that's the case???

I'm using #1 fixed only. Yes jumpering all the out posts. Tried that but that's where the problem lies.

Don't jumper the posts, just use fixed 1 and hook  the U connection from the TMCC base  to an outside rail on fixed ones track. Try your Proto-3 now, Should work.
