Page 17: Select And Run An Analog Loco On Address "00
4.5 Select and Run An Analog Loco on Address “00” 1. Place an analog locomotive (one without a decoder) on your layout. While the analog loco is sitting still, you will hear the characteristic “singing” caused by the DCC track signal when it is applied to analog locomotives. Once the analog loco is moving, this sound will change and be less notice- able. -
Page 18: Select And Run A Decoder Equipped Loco
Each decoder has an address. To select a decoder equipped locomotive and run it on a throttle, you must know its address. Digitrax decoders are set up at the factory with the “default” 03. This means that when you take a Digitrax decoder out of the package and install it in your loco, you can select address 03 on your throttle and run the decoder. - Page 19 The illustration below shows the display after address is selected on the “00” and address is selected on the , We see the R Throttle “03” L Throttle TRACK in the top line, the speed bar graphs at 0 speed and the POWER Indicator On text area also at 0 speed for both throttles.

Page 22: Loconet: The Digitrax Difference
DCC, such as detection systems and transponding, are not standardized. LocoNet is a hybrid system that incorporates DCC and other technologies to expand the capabilities of your system. Your Digitrax system gives you the best of both worlds with a system that is compatible with today’s DCC standards and also goes beyond those standards to deliver enhanced sys- tem performance and advanced features that are far beyond the scope of DCC. -

Page 28: Advanced Installation Of Digitrax On Your Layout
Early proponents of DCC touted the fact that you can hook up your railroad with just two wires. While this is technically correct, there are some things you will need to consider to get the most out of Digitrax Complete Train Control. -
Page 29: Service Mode Programming (Using A Programming Track)
Programming Track With DCS100 6.2 Direct Home Wiring vs. Common Rail Wiring Digitrax strongly recommends direct home wiring where each power district and its booster are electrically isolated. This type of wiring is safer and more convenient to work with for debugging and for adding reversing sections and detection later. -
Page 30: Recommended Wire Sizes For Power Bus And Track Feeders
6.3 Recommended wire sizes for power bus and track feeders On an average size layout Digitrax recommends that the power bus from the booster be at least 16AWG. When feeding areas up to 50’ from the booster, we recommend using 12 AWG wire for the power bus. -
Page 31: Number Of Locos
2. Double gap the rails at each end of the power district and single gap for sub-districts within districts. 3. Connect a DCS100 or other Digitrax booster and power supply to each dis- trict. Use a PM42 with your DCS100s to set up sub-districts. -
Page 32: Reversing Section Wiring
6.7 Reversing Section Wiring You can operate reversing sections manually or automatically with Digitrax Complete Train Control using an auto-reversing booster, a reversing section controller such as an AR1 or PM42. You must double gap (completely isolate) -
Page 33: Using A Db150 As An Autoreversing Booster
automatic reversing will not cause analog(non decoder equipped) locos to auto reverse. If you choose manual operation, use a DPDT switch or relay to handle the polarity change as the loco enters and leaves the reversing section. If you choose to use a DB150 auto reversing booster to completely automate the reversing section, power the reverse loop with a DB150 and power supply and the main layout with your DCS100 and power supply. -
Page 34: Using Pm42 For Power Management And Autoreversing
If you are using two Digitrax boosters, one acts as the polarity reference and the other handles the polarity reversal for the reversing section. You can also use a DCS100 and PM42 to handle automatic reversing sections. -

Digitrax equipment from the layout and test it on a small section of track not connected to the layout to confirm that the problem is not with your Digitrax equipment. -
Page 36: Dcs100/200 Control Panel
Digitrax recommends the PS515 power supply to power all DCS100s and the PS2012 for DCS200s. There are many other power supplies and power packs that can supply the input power for the DCS100. Check with your Digitrax dealer for suggestions. Most regular DC model railroad power packs are not able to supply 5 amps to the DCS100 booster, because they were designed to run only 1 or 2 locomotives in a DC blocked system. -

Each of these CVs can be set up when your command station is in the programming mode. The CVs are remembered in the decoder until it is repro- grammed to with a different CV value. Please refer to your Digitrax Mobile Decoder Manual for a complete listing of the CVs supported by each decoder. -

Page 99: Decoder Status
Status editing is used most often when you are running non-Digitrax decoders that do not have 128 speed step capabilities. If you can’t get a non-Digitrax decoder to work on your layout and you are sure you are using the correct address for the decoder, you probably need to status edit it to run in 14 or 28 speed step mode. -
Page 100: Note For Non-Digitrax Decoder Users
If you have a decoder that does not have advanced 28/128 speed step mode available, you must “status edit” that locomotive to standard 14 speed step mode before running it with your Digitrax system. Changing the decoder’s sta- tus will cause the system to handle this decoder as a 14 step decoder. Status editing does not reprogram anything in the decoder. -

Active throttle: Digitrax DT throttles are actually two throttles in one. Each handheld can control two different addresses or consists at a time one on the right side or R Throttle and the other on the left side or L Throttle. The DTs display is shared by the two sides of the throttle. - Page 106 Analog Mode Conversion: When a Digitrax decoder does not see DCC pack- ets on the layout it changes automatically to DC operation. Not all DCC sys- tems support this feature so you may have to program non-Digitrax decoders to operate on analog layouts. Automatic analog mode conversion can be disabled by programming CV29.

Configuration Variables (CVs): these are special storage locations or “pigeonholes” in your decoders. By programming values into various CVs, you can control each decoder’s performance characteristics.

- Page 112 Recall stack: Digitrax Release: Refreshed (Data): Digitrax command stations re-send data to decoders many times to be sure that the signal is not lost and that you have reliable operation. All in-use and common locos in the system will continue to be refreshed until they become idle.
- Page 113 Status Editing Decoders: a DCC decoder’s status can be manually changed by a Digitrax command station at any time the decoder is selectable. Stealing a Loco: overriding the in-use interlock and forcing the throttle to select an in-use loco. This can result in having two throttles logged on to and controlling one address.
- Page 114 Transponding: The use of transponders installed in rolling stock and transpon- der detectors installed in the layout to allow the system to determine the loca- tion of a particular piece of rolling stock on the layout. Other information about the rolling stock such as speed, direction, etc. can also be determined. Transponding is useful for automation of staging yards, dispatching and for realistic sound systems.
