Re: Source for Track Bus Twisted Cable

Beldden 9411 is indeed twisted pair (my bad), but do you want to have to open the outer sheath everywhere you want to attach droppers?  On my NTRAK modules I just use 12 Gauge zip wire and forgo twisting.

Re: Source for Track Bus Twisted Cable

dstuard@...
 

In the telecom industry "twisted pair" generally refers to premise telephone wiring, usually 24 gauge or smaller.  It also includes 26 pair cable, where each pair is twisted to reduce crosstalk between pairs.  For DCC track bus use you generally want 14 gauge or so, which does not come a "twisted pair" unless you twist it yourself as others have suggested.  Note that there is no general agreement on the need to twist.

There are so many other sources of electronic components, why waste bandwidth on Radio Shack? At one time they were a leader for the electronic hobbyist. They wrote their own obit!

Guys,
   I used to be a Comm guy, guess I still am but there is an easy answer. Measure all the lengths you need and get a total,  little extra wouldn't hurt and head for Lowes's or Home Depot or your local hardware if they have a spooler. Menard's around here doesn't sell cut wire.
   Here is the procedure, pick your colors of stranded wire, put a piece of bright tape where the wire starts, have it wound into a spool, take your wire home and drop it into a bucket or a snug box.
   As you pull the wire from the box or bucket it will be twisted maybe 2 or 3 twists to the foot. It isn't much but the important part is that it is inconsistent so it is never parallel to the previous or other pairs.

The DCC requirement is 3-5 turns per foot. I do not know what the commercial
twist is, but if you have to untwist, making you own might be easier.

I am rewiring my track bus and would like to find a source for 2-conductor
14 AWG twisted pair wire. I have looked at a number of online hobby and
electronics stores, but can't seem to find this size in twisted cable. I
will be running my layout with the NCE PowerPro throttle + SB3a Booster (5

the larger size. Suggestions?

Marvin,

Buy some 14 AWG and twist it your self using an electric drill. Twist as you go along or it will be difficult to add the feeders.

Hello Marvin,

Belden 9411 is a 14 guage twisted pair.  


 I do know that fire alarm cable comes in 14 AWG but not sure it if it considered twisted pair. There is some speaker wire that might be twisted pair.  

I did not worry about the twisted pair on my layout.  I bought 12 AWG stranded in Red and Blue colors and ran them together under the layout and everything has been working just fine.

Re: Screw Terminals for Main Bus to Sub Busses

Now that I have a new ISP and working Internet again, I can respond to this post.


There is no one right way to distribute DCC power.  One way is to use barrier terminal strips.  See the parts section of my website at:  Wiring For DCC - Parts


As Don V. mentioned, you can use a wire and loop through the screws to make a distribution strip.  If you want to spend a little money, you can use jumpers made for this purpose.  See the parts section in my website for these jumpers.

Grounding strips from a big box store. No need for any barriers since they are all connected together

Re: Screw Terminals for Main Bus to Sub Busses

John
 

Glenn,

Thank you so much! That barrier terminal block strip is exactly what I was trying to find. I just couldn't find the name. My NEC/DCC only has a single wire out and I need to break that main bus up into sub bus lines. I think this will work perfectly.

Re: Screw Terminals for Main Bus to Sub Busses

Glenn
 

I believe what you are referring to is called a barrier terminal
block/strip.

What you need to do with it is to take a length of bare wire and snake it
between the out going terminals on one side. Also connect the incoming main
bus to this side.

These terminal strips come in 2 and higher pairs of screws. You could easily
separate the input side into two sections.

Don has provided a jumper strip; RS also has an eight position barrier strip
with a corresponding jumper.
http://www.radioshack.com/nte-25-b600-08-8-pole-panel-mount-dual-row-termina
l-block/55055501.html#.VRwPEfCV5ic
Their part numbers: Block: Model: 25-B600-08 Catalog #:55055501, Jumper:
Model: 274-650 Catalog #:2740650

The jumper can be cut in half, just make two cuts so there is a gap between
the two halves.

I haven't tried recently, but you could order through a store and have it
sent there thus saving shipping.

NOTE: Radio Shack has gone through some changes leading folks thinking they
are going out of business. My two local mall stores closed, however they
just opened a new store in a less upscale strip mall. There you can park in
front of the store instead of fighting through the mall crowds.

Radio Shack has a 'jumper strip' (p/n 274-650) that connects up to 8 screw
terminals on one side of a terminal strip together to form a distribution
bus. You can do the same thing on practically any terminal strip by simply
looping a bare wire between adjacent terminals. There is a PCB specifically
made for the purpose for model railroads. See Miniatronics PDB-1. You may
also find a multi-tap 'grounding' connection bus bar in the electrical
circuit breaker section of your local Home Depot store, or equivalent, that
will meet the purpose when 2 of them are mounted to a piece of wood.

Subject: [WiringForDCC] Screw Terminals for Main Bus to Sub Busses

I have determined from all my reading that I want my main bus to go out to a
screw terminal and then have sub busses go out from there. But the only
screw terminal I've seen is from radio shack and from what I can tell has
screws. Six on a side . So it would just send back out the same signals
that are on the other side.

I think I want one set coming in and however many subs I need coming out.
Does someone make something like that or am I confused?

Re: Automatic Balloon Track Control using DCC auto-reverser

John Sawaska
 

All I can tell you is what works well for me. I have a large reverse loop with two entry/exits. The turn outs are controlled by tortoise switch machines with hare decoders and the loop is controlled by a PSX-AR. You can enter the loop from either direction and when you get to the exit turn out it will align its self for the train to return to the main line going in the opposite direction. The points will return to the closed position when the next train approaches from the direction opposing the points. I have had zero problems other than I wish that I had placed the trigger rails (for the hares) a little farther from the turn outs.

Thanks for the explanation. The black box does have a knob on top, which probably times the pauses. Charles

Re: Automatic Balloon Track Control using DCC auto-reverser

Jim, if you have not already acquired the reverser and the lay, you might want to look at the DCC Specialties HARE at Tony's Train Exchange.  It will do exactly what you are trying to do, but it is all in one unit.  Only extra you need is a SPDT (Monontary) center off switch.
