Hello,

Here is my model railroad (The UP/BNSF): HO scale, PS2012, DCS200, PM 42's (5 installed, 3 for Power Management, 2 for reverse loops), BDL168's (4 installed, 37 blocks in layout), DT400R's ( 2 DT400R's, 1 DT402R), UR91 (no problem with track status indicator interferring with radio or IR), UP5 (2), Programming track as a siding, 30 turnouts (all powered by Tortoises), DS 64's (8 installed and powered but not yet wired to Tortoises), 19 PS 12's (1 each for the PM 42's, BDL168's, DS64's, UR91, 1 splitting power to each of the UP5's), 18 locomotives (All with sound; 13 Tower 55's, 3 Atlas, 1 Athearn Genesis, 1 MTH), Rolling stock (190 cars), Track (500 feet), SE8C (as many as needed will be added for complete signalling and routes).

Everything works great on my layout. I am modeling contemporary freight, just like that which rolls through Rochelle, Illinois every day. I can pull 25 cars up nearly 3% grades with 2,3, or 4 consisted Tower55 ES44AC's). I can run all 18 locomotives, but not in the same block which I understand and apprecitate.

I have not taken a locomotive onto the programming track and "messed with the CV's". I have gone into the PM 42's to adjust the option switches for the reverse loops, but beyond that, I have not utilized the DT400's beyond running the trains.

I have planned this layout for 20 years, been building it for 10, and have gotten through all of the glitches which were my own errors. I have read the manuals, but reading a Digitrax manual doesn't mean I have learned it all even with my Mechanical Engineering degree. DCC is as difficult as graduate level Thermodynamics and don't let anybody tell you otherwise.

I have some questions: Does each stationary decoder get an address? Are my DT400's stationary decoders? If so, how do I give each DT400 it's own address? I cannot find the specific instructions for assigning addresses to each stationary decoder anywhere in the manuals or online. I am about to assign addresses for each of my turnouts, but do I assign a seperate address for each DS64 before I assign an address for each turnout? Does each PM 42 and BDL168 need it's own address? Please point me in the correct direction.

This is indeed the world's greatest hobby.

Hello Steve,

Well, that was a long way around to your question.

Digitrax accessary boards do get assigned a unique Board ID. The instructions to do so are found in the manual for each board. You should not overlap board IDs as a general practice. For the BDL168s it it imperative that they have unique IDs as that is the basis for their reporting occupancy.

It is generally a good practice never to leave a board at its default address. On my layout I have SE8Cs in single digits, DS64s in two digits, and BDL168s as three digit Board IDs. On DS64s, turnout address are independant of Board Id.

It is a good idea to write everything down and use a logical approach when assigning IDs. I suggest using LocoNet Checker to monitor them and do all programming once Board IDs are assigned. You can then keep a record of all the settings on the computer.

In answer to your question about DT400s, you can assign each a unique ID if you wish, but it is not absolutely necessary. Instructions for doing so can be found in section 21.1 of the DT400 manual.

[DS] A stationary decoder primarily controls turnouts. Each turnout or device needs an address. Some decoders allow each controlled device to have a unique address (DS64), while others implement sucessive addresses based on board ID (SE8C, DS54). Board IDs are not addresses per se, but often are used to determine device addresses and/or identify unique sensoe inputs.

Are my DT400's stationary decoders?

[DS] No, they are throttles, and have no addresses of their own.

If so, how do I give each DT400 it's own address? I cannot find the specific instructions for assigning addresses to each stationary decoder anywhere in the manuals or online. I am about to assign addresses for each of my turnouts, but do I assign a seperate address for each DS64 before I assign an address for each turnout?

[DS] All turnouts need an address. Board IDs for DS64s only need to be assigned if you use them to provide turnout or detection sensor messages. That said, it is generally a good idea to assign a unique board ID to each DS64 for programming convenience if using software such as LocoNet Checker or JMRI DeciderPro.

Does each PM 42 and BDL168 need it's own address?

[DS] See above. > > This is indeed the world's greatest hobby.

It sure is (and Go HOKIES!) ;^)
