Back EMF/Digitrax

== Consisting Digitrax Multifunction Decoders with BEMF ==
When using Advanced Consisting, Digitrax multifunction decoders disable their BEMF. This occurs when CV19CV19 is the consist address. If this is set, the vehicle will not respond to its primary or extended address. is a non-zero value.
 Digitrax splits the CV used for BEMF adjustments into segments for controlling the BEMF whether consisted or not. See the Digitrax Decoder manual for details.
Some Digitrax multifunction decoders employing CVs 55 – 57 (Scalable Speed Stabilization) may set CV57 to 0 (Off) when used as part of an Advanced Consist. This results in more throttle required to get the locomotive moving, creating conflicts within the consist.
=== Digitrax Variations ===
Digitrax provides several options:
# It can be turned on and off at will. 
# A certain amount of tolerance can be programmed in – in two different ways (making it scalable); how much Back-EMF to use and how fast to use it. 
# And lastly, they provide for two different amounts of Back-EMF to be used based upon whether the loco is consisted to another loco or not. This last feature allows you to program full Back-EMF control when not consisted, and have some tolerance for the other loco when consisted via Decoder-Assisted Consisting.
Like all things with versatility, Digitrax's Back-EMF is a little more complicated to program than others. Think about it. If can only be turned on or off, that's all you need to learn how to do. Digitrax's Back-EMF decoders can be operated in this manner. When running two locos together under Back-EMF control, it is necessary to learn how to program that feature into the decoders as well.
To do all of this, Digitrax uses three CVs (55, 56, & 57). To explain how each of these works, you must understand that the "target" speed is the speed with which the locomotive is supposed to be going according to the throttle setting. 
# CV55 is used to tell the decoder how fast to compensate for speed differences. 
# CV56 uses historical information to act as a shock absorber - to keep from over reacting. 
# CV57 tells how much tolerance from the target speed is allowed. 
## CV57 is divided in half. The first hex digit is for how much Back-EMF is applied when not consisted, the second digit controls the amount when consisted via Decoder-Assisted Consisting.
Ballast

Ballast is aggregate which provides a base for the track. This allows the track to contract and expand with changing weather conditions, while keeping the track in place and providing drainage. In real railroads, ballast must provide a stable, raised foundation for the track which must carry a heavy load and various forces resulting from the movement of the train. Ballast is also used to level uneven terrain. Part of the track maintenance includes replacing and cleaning the ballast. (See Pentrex's Working on the Railroad DVD for more on track maintenance.) 
On our scale railroads ballast serves the same basic functions. Indoors, ballast is used to fix the track in place and give the appearance of real track. The track is affixed to cork or foam roadbed to provide the correct profile, and ballast made of stone or the crushed nut shells is applied and fixed in place.
It is important to remove any metallic debris from the ballast to avoid short circuits. A magnet can be used to remove ferrous metals, but others such as copper an aluminum will remain. Commercial ballast should have been processed to remove any metal fragments. Also, during the process of fixing the ballast with glue, the result may be conductive until it dries and the water has evaporated. 
In some outdoor large scale installations, track is fixed to a sub foundation (wood, concrete, etc.) and the ballast is decorative in nature. Outdoors, over time, our scale ballast tends to wash away and must be replaced.

Bus

A specific group of electrical wires that carries a particular group of voltages or signals between devices. The term is borrowed from computer engineering. The power bus could also be compared to the busbars, heavy copper bars, used to conduct electricity at high currents in the electrical industry.
An example would be the power bus that supplies voltage and current to the track, running in parallel with the track and connected at multiple points using feeders. 
Another example would be a throttle network such as LocoNet, which connects various devices together into a network, allowing communication between devices.
A common misspelling is buss. The correct spelling is bus.

Digital Command Control
Layout Command Control
WiFi
RailCom support
Cab Bus support
CAN Bus Support
XpressNet Support
The number of throttles supported is dependent on the connection method. WiFi is included for wireless throttles, and LCC can also be used for throttles.
Booster output is claimed to be 5A continuous.
As a WiFi access point, range is 100ft.
As this is a new product, others are welcome to update and expand on this article.
CS2B

The main command station from CVP Products is the CS2-B. The latest firmware is 629 released in 2007. It uses a CR2016 coin cell for backup and can handle 255 locomotives in memory. It provides a programming track output, RS232 port (with special cable, not included), Booster output and throttle input ports. Cabling between these items is from 6P6C modular cable and one can easily make their own with off the shelf crimping tools. 
The CS-2B with 629 firmware allows for NMRA F0-F12, improved throttle response times, optional software deactivation of many RS232 functions which further improves throttle response times and was given an NMRA compliance warrant for meeting the NMRA DCC standards.
The EasyDCC system is fully compatible with DecoderPro software through the use of the included RS232 port. However, a special cable from 6P6C to 9-pin RS232 is required and can be easily made with the proper tools.
CV Readback

Some command stations allow the read back of CV contents. This can be used to check parameters or verify the value was accepted. 
CV readback is not possible during Operations Mode ProgrammingSometimes called "Programming on the Main" or POM. and is primarily accessible during Service Mode Programming when a locomotive is on a programming track. 
 Exception: Digitrax multifunction decoders equipped with transponding when used with a Digitrax system supporting transponding can read back CV values during Operations Mode programming.

Cab

A Cab is the (typically handheld) device that is used to control a train. A basic cab has controls for speed, direction and a few other functions. More sophisticated cabs have more functions including the capability to create consists and program decoders. CAB is the preferred NMRA definition for the control device. The term is derived from the fact that the operator has all the controls the engineer has in the cab.
Cab Control is an old analog method, which involved a lot of electrical wiring and switches to connect the cab to the train the user was controlling.
See Throttle.
Cab Control

Category:DCC History
Cab Control is a term used for Direct Current (analog) power management. The throttles are referred to as cabs. 
During operation, electrical switches are used to route power to blocks. The Digital Command Control equivalent is a power district. The switch controlled which cab was connected to its block. More complexity meant more switches (and wiring) to connect the cabs to the track. 
During operation, the operator would set the switches to connect/disconnect his cab to the block. As the train progressed down the track, the cab would be connected to the blocks needed, and the operator would disconnect his cab from those blocks he had left. If a train entered a block with no assigned cab, it would stop. If the block were assigned to another cab, the operator would lose control of his train. 
For a large layout, someone may be assigned to the Dispatcher job, having control of all turnouts, signals and blocks with the task of keeping trains rolling. The Dispatcher would be at the Central Traffic Control panel, often with no view of the layout. CTC is a large expense and very complex to implement, so only large layouts featuring Class 1 operations would have one.
Other implementations include Progressive Cab Control, where power routing for a cab was done automatically, usually by a computer driving relays, and Master Zone Layout Control.
==Differences in Digital Command Control==
 Digital Command Control implements blocks as power districts. They do not serve the same purpose as blocks would in cab control situations. Power Districts are used to isolate multiple boosters or to manage power distribution and isolate faults from the rest of the layout. In DCC, unlike cab control, multiple trains can be operating in the same power district, controlled by multiple operators. 
This directly enhances operations, as the engineer no longer has to worry about trespassing in another block, and various prototypical operations can be replicated easily. No longer is a long cut of cars needed to move a few cars because the switcher can't come into your block, and can't reach the needed place without them.
==Dispatcher==
According to the Flagstaff Model Railroad Club, the Dispatcher's duties include:
* Maintains final authorization over the movement of freight and passenger trains. All operators must obtain permission from the dispatcher prior to movement of railroad equipment anywhere along, or involving, the main line. 
* Responsible for operating block control and mainline turnout toggles on the dispatcher's booth control board. 
* Communicates with each yard master regarding train movements into and out of yard limits.
Can Motor

A can shaped direct current motor.
The stator is built using permanent magnets, the rotor has windings which are energized during operation. Polarity of the windings is controlled using a commutator and brushes.
Most Direct Current motors used for models are permanent magnet motors. 
When operated using zero stretching, the motor will hum. The motor may also hum when the decoder supplies pulses for low-speed operation, adjusting the CV that controls the pulse frequency may minimize or eliminate it.
Some are 5 Pole Skewed motors. The rotor has five poles, which are skewed, for better low speed operation without cogging.
See Motor.

Club:NMRA PNR 4th Division NTrak Modular Group

Sponsored by the NMRA Pacific Northwest Region 4th Division, we are the 4th Division NTrak Modular Group aka "4DNtrak".
All members are required to hold NMRA membership.
==Club Background==
The 4th Division N-Trak Modular Group has been up and running trains for five years. We have twenty members and over thirty modules. The 4th Division supplied our four corner modules and a "starter" yard. All modules are framed, wired, and sceniced. We added the spectacular yard in 2004 with 6 20-foot through loops and 10 6-foot stubs. We now have enough room to handle many prototype-length trains.
We welcome all skill levels from expert to beginner. For those of you looking for a way to try out the hobby or to get a little practice before you start on your own layout, come on down and join us. Modular railroading is a great way to get started. Even if you think you don't have room for a layout, you do have room for a module. They're the size of a card table and you can set them up and tear them down easily.
==Club DCC Activities==
Since June of 2007, 4DNtrak has been a DCC only club. We use the Digitrax System and have two "Blue carts" that sit at either end of the layout.

===February 2006===
* February 10-12, 2006 - Gateway Garden Railroad Club Winter Meet - Large Scale Train Lovers:
Four years ago, Gateway Garden Railroad Club members decided that February would be a good time for a large scale train meet. Everyone has cabin fever by then and is ready to run some trains. With the help of other club members the Gateway Garden Railroad Winter Meet was born.
Every February the town of Carlyle, Illinois becomes ground zero for a gathering of Large Scale Train Lovers from all over the Midwest (those outside the Midwest are welcome too). This meet is about running trains, building friendships, and learning from each other, not making money. What little is charged is to defer some of the expenses incurred by the Gateway Garden Railroad Club.
Everything is convenient. The Microtel Inn (where most attendees will stay, reasonably), the indoor convention center (where the meet is held) and a great country restaurant (where you will never under eat or pay too much) are all within 100 yards of each other. Other facilities (restaurants, stores, motels) are available in the area.
There will be a few vendors for the convenience of the attendees. The amount of space allocated to vendors is strictly limited to allow plenty of space for layouts (where you can run your train), clinics, and work areas. We encourage attendees to bring things to run and pull. We want to share your handy work!
===March 2006===
* March 31-April 2 - East Coast Large Scale Train Show at the York Fairgrounds, Memorial Hall East, York, PA. $25 ($22 for members) for all days, or $10 each day.
Command Control

Command Control allows the independant control of several trains without altering track voltages or using blocks. It is a generic term the describes many different systems offered over the past 60 years.
The first command control system was introduced in 1946 by Lionel. The next major leap was ASTRAC from General Electric, a transistorized system. These systems are best described as carrier command systems, or another term would be analog command control.
Others would follow, all using some form of high frequency carrier or tones carried on the track to control a locomotive. Analog in nature, these systems were costly, limited in features and often completely incompatible with any other system on the market. Even upgraded versions of a command control system were, in many cases, incompatible with the previous system, sharing only the name. The level of technical skill required to set up and maintain a command control system was often a liability that prevented widespread adoption. The first digital system used an analog computer, adding complexity to an already costly system.
Command control never gained a significant share in terms of modellers abandoning the traditional analog (Direct Current) control technology for it. Within that segment there was no clear leader either. The primary reasons were cost and compatibility.
DCC, or Digital Command Control, is the name applied to the NMRA's standard for digital command control. The term Digital was added to differentiate it from the other, mainly analog command control systems on the market at the time.
