The PM42 will certainly do the job, as it can be run independently
from the loconet, but you will need a digitrax throttle to change
any of the settings.

Keep in mind that when a PM42 section is configured as an auto-
reverser, it does not provide short circuit protection (it reverses
the voltage polarity, rather than disconnecting it). Your booster
or other power manager must provide that function.

You might want to consider a PM42 used as a power manager/breaker
followed by AR1 revering modules for your reversing sections.
Another approach would be the Power Shiels and PSRev products from
Tony's Trains. See
http://tonystrains.com/products/tteexclusive_pscb.htm



This is all new to me and at times very confusing. Do you have
any

Read, read, read...If you can get hold of "The Big Book of DCC" from
Digitrax (now out of print, but an updated version is due "soon").

Also, the following dealers have good intro material:

Tony's Trains:
http://tonystrains.com/tonystips/dccprimer/index.htm

Loy's Toys:
http://www.loystoys.com/MiscHTML/dcc-topics.html

and Litchfield Station:

After that, Google can help you get as deep into it as you want.

Thanks for your replies. Yes, I actually have 3 auto-reverse areas and 1
turntable, this is why I was going to use the PM42. I'm using a NorthCoast Pro
DCC unit. Reading the forum I think I would need a DigiTrax throttle to
change any settings to make the PM42 an autoreverse module. Is there any way
around this using the Northcoast since I've already purchased it?

I still have the option to return the PM42 and go a different route.

Is it better with DCC to stay with the products that are the same brand as
your control unit?

Marcus, I will be using the autoreverse module as a return loop. Do you
have any suggestions?

Re: AutoReverse Modules

Marcus Ammann
 

Hi Paul

It depends on whether your sections of track that need voltage polarity
reversing, enter and exit by the same turnout or different turnouts.

For a section that enters and exits the same turnout, I call this a reverse
loop. For a section that enters and exits by DIFFERENT turnouts, I call this
a return loop.

Auto reversers are expensive, so for the "reverse loop" I use a DPST (double
pole single through) switch or a relay that is connected to the operating
throw bar of a turnout. The train enters the reverse loop and to exit the
reverse loop you will have to operate the turnout. This is normal. Operating
the turnout will also operate the switch/relay that will change the polarity
of the track voltage. The train will continue as if nothing happened.

So for a loop that is used for changing the direction of the train a switch
will achieve the same as an auto reverser.

The "return loop" is a different proposition due to the layout construction.
The return loop may be at the end of a yard where either the yard or the
return loop voltage polarity has to be reversed. This can only be done
automatically and easily by using an Auto reverser.

Turntables are another example where an auto reverser and not a switch must
be used.

Re: AutoReverse Modules

Marcus Ammann
 

Hi Paul

As you have an NCE system, like me, for an auto reverse unit you must use a
DCC manufacturer not the same as your system. NCE does not make any auto
reversers and have them marketed under the NCE brand. There is no
alternative.

The Digitrax PM42 will most probably work on NCE, but if it required
"adjustment", then this could only be done with a Digitrax throttle.

For users of any DCC system, other than Digitrax, I would only buy units
manufactured by anyone other than Digitrax. These include Tony's Train
Exchange - PS Rev Power Shields. MRC's - AD520 and Lenz's - LK100.

See Tony's site for details for auto reversers at:

http://www.tonystrains.com/technews/dcc_autoreversers.htm

For using the auto reversers on return loops see the above site and Allan's
site at:

http://www.wiringfordcc.com/track_2.htm#c4

There are no cheap and simple solutions for "return loops" that operate
automatically and "transparent".

My recommendation for an auto reverser would be Tony's PS Rev. These are
solid state electronic units. I have seen and others have reported problems
with using mechanical relay types of auto reversers. They may cost a little
more but they offer trouble free operation to everyone that uses them.

Marcus.

Yes, you do need a Digitrax throttle to configure the PM42. You
might be ablke to find an old DT100 or similar for a song, so it
might not be that bad.

If, however, you still can return the PM42, PowerShield and PSRev
units from Tony's might be a better choice in your application.

Feeder Tester

jmscnw <jmscnw@...>
 

After attaching all feeder connections , is their a tool available
to check all the feeder connections around the layout to make sure
they are supplying power and data ?

Re: Peco Setrack 100 for DCC

wirefordcc <wire4dcc_admin@...>
 

Dianna,

I've never heard of the Peco Settrack. If I am understanding the
description of your problem, it sounds like the rails leaving the frog
need insulated joiners on them. This would make the Settrack like the
Peco Electrofrog. The Electrofrog is on my website at:
http://www.wiringfordcc.com/switches_peco.htm#a2

Give the insulated joiners a try and see if that solves your problem.
There is no risk in you trying this. It won't harm anything if this
is wrong.

Allan

Re: Feeder Tester

wirefordcc <wire4dcc_admin@...>
 

Probably the best tool that your feeders are adequate costs 25
cents. Yes, I'm talking about using a quarter. If your booster
shorts out promptly when you place a quarter across your rails, you
are good to go. You can use a screwdriver or a pair of pliers,
too. This is a test everyone should run when through hooking up
feeders. It really is a good indication of the quality of your
connections.

If you are worried about the data being corrupted, after your short
test, try a locomotive with a decoder in it.

If you are worried about excessive voltage or ringing on your track,
try building the ultra simple circuits I describe in my website
at: http://www.wiringfordcc.com/track.htm#a4 or buying a DCC meter
from Tony's Train Exchange.

I've never needed anything else. And after successful testing with
a quarter, things have always worked for me.

Re: Peco Setrack 100 for DCC

cptracks
 

Setrack is supposed to be Peco's version of snaptrack. I have used some Setrack turnouts and they were insulfrog. To be honest I also took them all out. They have a sharper radius than the normal Peco units and I thought I could use them in my industrial areas plus one area on the main where a sharper radius would really be a benefit (so I thought, first layout with very limited room, can you tell?). They worked fine for 4 axle diesels and most 6 axles, but Lord have mercy when I tried to run steam through the inside track. They are gone, gone, gone. I lost some room and trackage I really wanted, but the trade was worth it to me. I guess it all depends on what you want to do.

Re: Peco Setrack 100 for DCC

Dianna Lee Sharps <diannaleesharps@...>
 

Colin,
Your quite right. The layout is the Jerome & Southwestern by John
Olson. The original plan is from 1983 and a lot of the parts are no
longer available, the Atlas double radius switches being the big
problem. They worked out between a number 4 & 5 and the Peco Setrack
was the next best thing I could locate. I have a 2-4-2 that makes
it ok but I've found that if the wheels arn't perfect you'll catch
the frog. I'm going to see if I can fit the Peco double radius but I
don't really want to re-lay half the layout.

Bus design and termination

Earl T. Hackett <hackete1@...>
 

On the EasyDCC group I ran into a reference to Allen Gartner's web
site in response to another member's question. There I found
confirmation of waveform distortion problems I suspected from first
hearing about DCC. Right now I'm in the middle of a big (REALLY
BIG) rewiring job. To simplify trouble shooting and trackwork
modifications, the trackage is being broken into smaller sections
(20' to 30' with no more than 4 turnouts) that are individually fed
through DPDT toggle switches mounted on three local power
distribution panels. Sections of track that are signaled and
interlocked with the turnouts have their block detectors located in
an array directly adjacent to the power distribution panel. Most of
the local distribution wiring doesn't exceed 30' in length
(including the rails). However, getting the power from the boosters
to these distribution panels currently uses 12 ga. 2 conductor wire,
one with a length of 80'.

All the wiring is easily accessable so it would not be difficult to
pull out these heavy distribution wires, twist them, and put them
back in place. Currently one of these serves two local distribution
panels, one about 25' along and the other at the end of the 80'
run.

Q1: Currently each local panel distributes power from all of the 3
boosters; EB and WB main, and yards. Would it be preferable to have
a booster supply a single local panel and have heavy twisted busses
running to each local panel? I'm looking into the possibility of
moving the boosters from their central location to the distribution
panels, but then I have to make sure the signal being supplied to
them has not been distorted.

Q2: The local distribution busses from the toggle switches to the
track are essentially impossible to twist as there is a wire drop
from every piece of rail. Although they aren't very long, there are
a lot of them - about 50 blocks. Would there be a problem placing
an RC termination on all 50 local busses?

Q3: Assuming I run individual twisted main busses from a booster to
the local panels, should there be an RC filter at the end of the
twisted pair or should these RC filters be restricted to the most
distant point of the various local busses?

This is not what I consider fun so I really want to get it right so
I don't have to go back for another dose. Thanks for the help.

Terminating busses

Earl T. Hackett <hackete1@...>
 

Well, I managed to answer most of my questions pretty quickly once I
looked up the specification for the booster wiring.

The boosters can be placed at any distance from the command station so:

- The heavy distribution busses are gone as of about 15 minutes ago.
- The boosters will be moved to the various power distribution panels
and will be used to power all track in that general area - EB, WB, or
yard.
- A 4th booster will be purchased and used for the staging tracks
which are located in another room.
- Since I've only rewired only a couple of blocks, they'll be pulled
out, the bus wires twisted, and an RC filter placed at the end.

Twisting the pairs also helps find the wire pair supplying the block
if I ever need to track them down again.

Any problem with the above changes??

It seems that we should be describing the number of boosters required
based on the length of the power runs rather than on the amperage
required to drive the anticipated power requirements of the operating
locomotives.

Very briefly I use a Lenz LS150 (DECODER) to power a Peco PL10 switch

Re: Need basic info regarding switches for Bachmann DCC

wirefordcc <wire4dcc_admin@...>
 

John,

You found the Wiring For DCC Q&A Forum. Hopefully that means you
found the WIring For DCC website. It is at www.WiringForDCC.com.
It includes a section for beginners as well as other information you
should find useful.

The DCC device that can control turnouts is called an accessory
decoder or a stationary decoder. These are made by many of the
major DCC equipment manufacturers. You do not have to use one made
by the manufacturer of your command station. However, there may be
programming issues if you use one made by another manufacturer. So
be sure to ask and know how you will program it before buying.

You mentioned you have a Bachmann system. I don't have any
experience with the Bachmann system. You do have to be careful that
many of the starter systems cannot control turnouts. You need to
resolve this issue before doing anything else.

Just because you control your locomotives with DCC, does not mean
you have to use DCC to control your turnouts. Many, if not most,
modelers do not use DCC to control your turnouts. For one thing, it
costs about $15 to $30 extra per turnout to use DCC. This
understandably scares away many modelers. I personally use DCC to
control my mainline turnouts, but do it the old-fashioned way for
all others. In my case, using DCC turnout control with position
feedback gives my dispatcher control of the mainline. To operate my
industries there is no advantage to using DCC to control the
turnouts so I don't.

Re: Terminating busses

wirefordcc <wire4dcc_admin@...>
 

Earl,

We have two people who have a lot of experience with twisting buses
and terminations. I suspect they are both on vacation this week. If
they are not too swamped when they get back, maybe you will hear from
them next week.

You have done what I have done - located my boosters near the district
they power.

While you could figure booster need based on wiring length, I don't
think you need to do so in most cases. Twisting and adding
terminations allow you to go greater distances. Even if you hold to
30' maximum, if you put the booster in the middle of a district, that
means that district can be 60' long. That suits most people.

Allan
