Mobile Decoders

DG583S - Function Outputs 1. Function outputs are rated at 2 Amps each. Do not exceed the decoder’s 5 Amp total output rating. This total includes the motor current and total of all function output currents.2. To use a function output with an inductive(coil) type load, see the Digitrax Decoder Manual for more information to avoid damage to the decoder.3. See the Digitrax Decoder Manual for full details of wiring 12-16V lamps, 1.5V lamps, and LEDs. Lamps that draw more than 80 mA when running require a 22 ohm 1/4 watt resistor in series with the directional light function lead ...

What Digitrax decoders work in the new Athearn N scale FP45? We recommend the DN163K1C, following the procedure below. One of our editors was able to successfully install both the Digitrax DN163K1B and DN163K1C decoders in the unit. We have determined that the chassis design requires that the decoder be installed backwards. The only problem this poses is that one additional step has to be taken when programming. Both the DN163K1B and DN163K1C decoders are the same footprint with the exception of the LEDs. The DN163K1B has T-1 3mm LEDs and DN163K1C has surface mount LEDs. When the K1B version ...

The DZ121 was discontinued in 2002.  There were some interoperability issues with Easy DCC, MRC and Lenz.  The exchange offer is no long valid.  This article is still published for reference only.At that time, Easy DCC, Lenz and MRC users could return DZ121's to Digitrax for no charge replacements that will work on their systems. There was no reason for Digitrax, Wangrow or NCE users to replace any DZ121 decoder unless they wre having problems.The text at that time:For Easy DCC and Lenz users who are having problems: To determine whether your DZ121 should be returned, read back CV07. A ...

DH165L0 fits Life-Like GP7, SD60 and many other locos with Life-Like DCC medium plug arrangement. 1. Remove locomotive shell, noting the orientation of the circuit board inside. (See Figure 1) 2. Unplug the the manufacturer’s DCC socket from the pins on the factory board. Remove the two screws that hold the board in place. (See Figure 2) Lift out the factory board and save the two screws for future use. 3. Insert the locomotive’s DCC socket onto the pins on the Digitrax DH165L0 decoder board. In this orientation, Pin 1 (the orange wire) is the lower left pin and Pin ...

Short Address Programming Note When programming the short address (CV01) in your DZ121, the decoder will automatically set CV19 to 0, CV29 to 0, CV 55 to 80, CV56 to 30 & CV57 to 0. This is done to insure compatibility with DCC systems that only recognize short addressing (2 digit mode). When using long addressing (4 digit addressing) these CV's are not affected.After changing the short address (CV01), you will probably want to change CV29 to 06 or another appropriate value based on your operations. You can do this on the programming track or, if you forget, you can ...

Installation Notes: 1. Do not exceed the decoder’s 500mA total function output rating. 2. If you plan to use functions F1 (traditionally a green wire) or F2 (traditionally violet), the return, also called +Common or Lamp Common, should be made via a wire carefully soldered to the Common (or blue) pin indicated as shown in Figure1. 3. To use a function output with an inductive (coil) type load, you must install a kick-back suppression diode across the connections. If controlling a coil type load, such as an electromechanical relay or motor, shutting the device off can cause an inductive kick-back ...

Installation of the SFX004/SFX006 SoundBugs into a DH165-Series decoder is easy, but it does require some care. The SoundBug must be properly oriented to the decoder. Here, the DH165L0: Here, an installation in a Proto1000 DL-109. In this orientation, the SoundBug sockets are to the right on the DH165L0 decoder: The SoundBug is plugged into the sockets of the DH165L0 decoder: Because the DL-109 is a diesel locomotive, it will not need the white synchronization wire. Everything is fitted into place. The SoundBug is shipped with a small piece of foam to protect the pins of this decoder. You may ...

This application note concerns the DA120 deocder, which began production in 1997 and was discontinued around 2000. The DA120 decoder that is being shipped with the Atlas locomotives has certain variables that are available for programming. These guidelines are provided for those who are using the Wangrow or Lenz systems for programming the DA120 decoders.The following variables were selected by Atlas to be offered in the DA120. These CV's are available to be programmed on the DA120:    * CV01 - Address    * CV02 - Start Voltage    * CV03 - Acceleration Rate    * CV04 - Deceleration Rate    * CV05 - Maximum ...

The DH165Q1 is set up at the factory to control six function outputs. The DH165Q1 is configured to control the forward-headlight F0F/white lead and reverse-headlight F0R/yellow lead for directional lighting. These two headlight function leads are current regulated for LEDs or lamps, with factory setting of approx 15mA, with no resistors required. Cut the ADJ link to increase headlight current to approx 30mA- see fig 5. Functions F1 (Green), F2 (Violet), F3 (Brown) and F4 (White/Yellow) are full track voltage and can be used by soldering a wire from the pad for the function you wish to use to the ...

Many thanks to Dick Sutcliffe, Superintendent BR &T Railway Co. for this application note!Install the DN121 in the tender   1. The tender is easy to open by removing two screws so you can pull the decoder out and put in a plug when running on DC layouts.   2. Use a piece of styrene to raise the decoder off the weight.   3. Notch the front edge of the tender frame to bring the wires through to loco (all power pick up is in the loco).   4. Split the loco frame to isolate the motor brushes, remove the contact springs in the ...
