Thanks Glenn You kind of hit on what I was wondering about. Not sure if I needed some kind of load (motor) on the decoder for my sprog to be able to talk to the decoder. I am trying to program decoders that I have laying around.  I could open up a loco and put the decoder in it  but that  would take some time . I have a old kato circuit board that has the 8 pin socket on it. I cut away what I did not need and just left the traces on the board I needed. I just think it would be nice to be able to just plug in a decoder and program on the fly.Thanks Glenn

It would be better to acquire a wiring harness with an 8-pin female socket. The pre-wired socket makes for a safer connection that to try and keep (assuming) alligator clips from shorting to other pins on the decoder. Pre-wired socket are available, but buy what your DCC source has available. An 8-pin socket attached to a 9-pin plug can have the 9-pin plug cut off.
 
Baring that purchase an 8-pin socket and wire it yourself. http://www.ulrichmodels.biz/servlet/the-452/8-Pin-DCC-Plug/Detail
 
Attach the track wires to pins 4 (Black Wire) and 8 (Red Wire).
 
You will also need a load on Pins 1 (Orange Wire) and 5 (Gray Wire). For a load I use and old can motor with a spoked wheel attached to the shaft. The spokes wheel allows me to see if the motor is running.
 
You can also use the remaining wires with LED’s / Lamps attached to test those functions.

Glen,
I don't see any "problem ". You need to explain what you mean by "management ". It doesn't take a sophisticated app to record what addresses are already in use so that the next guy can avoid duplication.

Hi Jerry,

It would be of benefit as to see how some people correlate physical names of stationery devices such as turnouts, signals and other devices to numeric addresses. I have a few ideas as to simplify it so one doesn't have to have pages of printed sheets in hand.

Seeing printed examples of other peoples could be of benefit.

It would be nice to see some examples from a beginners standpoint. This would save much time and effort is the learning curves to organize a fairly complex layout.


Len Jaskiewicz
 
Len, what sort of examples are you looking for?  Over the last two years I seem to have been through almost every oddity and glitch that can happen when wiring a large layout.  It all comes together eventually, and it isn't a bad experience per se, but there is a lot of learning.

Re: Address management for DCC device addresses

Vollrath, Don <dvollrath@...>
 

Greg,

Like the original railroads, it is up to the builder/user to keep it all straight. Organized documentation becomes more important with growth and changes. Since my personal RR has outlasted several versions of PCs, program apps and decoders I still use a master layout drawing showing all turnout and signal locations with their assigned addresses. Then there is also a master list of turnout, loco and signaling equipment addresses on an Excel spreadsheet with a back-up e-file and paper copy secured away for redundancy. Each turnout, loco and signaling device must have a unique address. Simply checking and updating the listings avoids duplication when changes or additions are made. Unfortunately all manufacturers seem to have their own way to make things work.

I use DecoderPro to manipulate and hold all decoder programming, including macros for an NCE command station.

I also use a spiral notebook or two to document ideas, sketches and notes in chronological order so that I can refer to them later. Having it all together in a notebook keeps key information together and organized. Pencils and pens still work.

I am just finishing up the physical wiring of my small Digitrax layout and am in the process of design/build for a control panel and signalling scheme. It hit me, while contemplating the rules for the signal addresses, that my layout is starting to look very much like a primitive network, like the early days of the Internet when one maintained and edited name/network address lists. Only with DCC there appears to be no management layer for the addresses or any logical name scheme either. But plenty of vendor-specific rules about address blocks and relationships.

 

While I recognize that for something like JMRI or Trainmaster to function all the addresses must be collected and embedded in its configuration. I refer of course to locos, stationary decoders for turnouts and other device control, signal systems and so forth.

 

Any software tools out there to help beyond yet another spreadsheet?

 

Thanks,

Re: DC Circuit Breaker?

wrhastings@...
 

Thanks for the replies. At this point, we are going to be powering Tortoises and accessory lighting (buildings and street lamps, etc.).

If the supplies are rated at 4 amps, what trip current should I be looking at, for Polyswitches?

Thanks, again

Bill Hastings


Re: DC Circuit Breaker?

Vollrath, Don <dvollrath@...>
 

Ross has a good idea. The Polyswitch type resettable fuse devices work well to protect wiring and other devices from long term overcurrent damage. For example they work great to protect twin coil switch machines from folks who like to keep the button pressed way to long. But they do not operate nearly fast enough to protect semiconductor circuits from high peak over current. However, they do have some internal (cold) resistance that tends to limit the peak short circuit current. Read the technical data sheets to find the best device p/n for your application. Several brands of competitive products exist. The DigiKey catalog (or google) is a good place to start. Having several ‘branch’ circuits each with its own Polyswitch fuse and a simple disconnecting toggle switch for servicing might be a less expensive way to go. You could put a miniature 12-14V grain-of-wheat lamp in parallel with the Polyswitch if you really want to know when/if the Polyswitch is limiting current. Be sure to mount the Polyswitch(es) in free air for best results. They do get hot when ‘tripped’.

We would like to install some circuit protection, preferably an auto resetting breaker. Do any of you have a recommendation on what we should use?

Re: DC Circuit Breaker?

If the power supply is regulated it probably has over current protection. In most designs the regulator either folds back or shuts down and recovers when the current burden is lifted.

Re: Constant Lighting Circuits

As I've heard it said, "The third time is the charm."  I can't tell you what might have gone wrong in my first two attempts, but obviously something did.  So I started over with new/fresh components, including a new and never used set of Tomar marker lanterns, and much to my delight, using DCC track power they lit up very nicely.

This success is for the first circuit from Wiring with DCC, without the flicker free element.  I will try the second circuit once I assemble newly acquired component parts.

For everyone who replied, thank you.  The process of learning new things with the help of others is one of the best things about this hobby.

George,

Have you tried to light one of the Tomar units recently with a 1.5V flashlight cell to make sure the bulb is not burned out. One mistake in wiring and it is gone.

I started with the first circuit but didn’t like the marker lights blinking as it rolled around the track.

I now have 2 cabooses with the 3rd LM317T constant current circuit working as shown with the 47 ohm current setting resistor. Visibly lit with room lights on, but not overly bright in a darkened room. No blinking or obvious dimming on a moving train. Energy cap is 6,800 uFD, 16Vdc.

A similar circuit works for tail lights on a streamliner car.

Tried the first and second circuits without success.  Checked my work several times, and then built new circuits with new components and still failed to get the Tomar lanterns to light?  I must be missing something, because I have received numerous responses to this site.  Although none of them have included a statement that says they actually used the circuit and that it worked as printed?

 

Thanks for the reply.

Re: Constant Lighting Circuits

The first and basic recommendation is to use a 1.5 vdc battery as the power source.  You can use track power, and it does require additional circuitry that Tomar does not provide in the kit.
