KB304 Kato RDC's and DN143K2

Photo Courtesy Kato, USA The DN143K2 replaced the earlier DN122K2 as a custom decoder designed for the Kato RDC in N-Scale. This is not a particularly easy installation and there have been some reports of problems with the headlights. Paul Lator has some experience with this installation, and this may be of help to you: "The wiring with the DN143K2 works well if you do not route the wires over the top of the seating in the RDC, rather completely disassemble the unit, mount the decoder in it's designated location then run the wires through the drive shaft tunnels. Place ...

KB294 Kato RDC Headlights Reversed

There have been reports of headlight problems with some DN143K2 decoders; the unit will be running in one direction but the headlights are backwards. There is a simple fix for this problem. Set CV33=2 and CV34=1; this will remap the function outputs F0F and F0R.

KB397 Installation of DN163K2 in Kato RS2 Locomotives

The DN163K2 will fit into the Kato RS2 and RSC2 locomotives with the same frame design. Installation for the Kato N scale SD90/43MAC is also similar.  Kapton tape should be applied in the saddle area of the frame above the motor to prevent shorting. Install the DN163K2 decoder into the frame by tilting it slightly as you insert the front corners into the forward frame clips. Press the decoder motor clips down over the motor contacts and slide the decoder board forward and press the board down into the frame. Be careful not to bend the motor contacts or let ...

KB398 Installation Instructions - Kato Nscale SD90/43MAC Locomotive

1. Carefully remove the locomotive’s shell from the frame. Notice the orientation of the light board, so that you can install the new decoder in the same orientation. 2. Carefully remove the factory light board by sliding it toward the back of the locomotive and out from under the frame clips. Then gently lift the board out of the frame. Be careful not to bend the motor contacts. Apply a small piece of Kapton tape to saddle area of the frame above motor. 3. Install the DN163K2 decoder by angeling it slightly as you insert the front corners into the forward ...

KB399 Installation of DN163K2 in Kato RS2 Locomotives

The DN163K2 will fit into the Kato RS2 and RSC2 locomotives with the same frame design. The decoder is also installed using these same steps in the SD90/43MAC. Kapton tape should be applied in the saddle area of the frame above the motor to prevent shorting. Install the DN163K2 decoder into the frame by tilting it slightly as you insert the front corners into the forward frame clips. Press the decoder motor clips down over the motor contacts and slide the decoder board forward and press the board down into the frame. Be careful not to bend the motor contacts ...

KB880 Installing Digitrax Wired Decoder in Kato N-scale AC4400CW

This article courtesy of Ken Bessler, concerning installation of a decoder into earlier Kato C4400W's.  Current produiction of these locomotives use DN163K1C or similar board replacement decoder.I wanted to convert my 2 new Kato AC4400CW's to DCC but there were several problems:1) The recommended PnP decoder, DN163K1a has a chip right where a shell component is. Using this decoder requires shaving off the plastic retainer clip under the exhaust stack. IMHO this is not good as it leaves too little support for the stack.2) My dealer was out of stock of the PnP decoders.3) A quick look inside the loco shows ...

KB17 DN143K2 - Installation Instructions for Kato N RDC's

Photo Courtesy Kato, USA Installation Instructions: The DN143K2 cannot be tested prior to installation in the rail diesel car. 1. Carefully remove the shell from the RDC. Carefully remove the plastic casting from the bottom side of the RDC frame, using a flat bladed screwdriver to pry it loose. 2. Gently remove the white clip that holds the seat panel in place. Remove the seat panel by pushing up gently from the bottom of the frame. The seat panel has clips underneath that are very easy to break, so be careful. 3. Take extra care to notice how the RDC ...

KB147 DZ125IN - Installation Instructions

1. Carefully remove the locomotive’s shell from the frame. Notice the orientation of the shell to the frame so that you can reinstall correctly. 2. Remove the 6 pin analog shorting plug and in its place insert the DZ125IN decoder with the correct pin-1 orientation. (There also is a small numeral "1" on the bottom of the DZ125IN near pin-1.) The DZ125IN has 6 pins that insert directly into the 6 pin socket (NEM 651 type) on the locomotive’s PCB. The DZ125’s small size allows the decoder to be easily installed in a variety of European locomotives. For the Kato ...

KB884 Wired Decoder Installation in Atlas/Kato GP30/35

These instructions detail the installation of a wired Digitrax decoder (a DN140 in this example, but many wired decoders may be used) into an Atlas GP35 manufactured by Kato prior to September, 2007.  These units are marked "Japan" on the bottom of the locomotive.  Units marked "China" use a board replacement decodr such as the DN163A2.Installation DiagramNotes:A. Be sure motor leads (Gray & Orange) do not touch frames & have protective insulation in place.B. Be sure frame is straight & mechanism is correctly reassembled & can turn freely without binding.Wired Decoder Installation InstructionsFollow these steps for decoder installation with either ...

KB886 Installation of Digitrax Wired Decoders in a Kato GP35 Diesel HO

Note: These instructions cover the hardwired installation of any Digitrax decoder with wires into a Kato GP35 H0 Diesel. Currently, the recommended decoder for current production GP35's from Kato are the DH163K0 board replacement decoder.  Using the board replacement decoders are much simpler and cleaner installation than the one described here.Tools Needed for Decoder InstallationYou'll need a few simple tools:1. A soldering iron, preferably temperature controlled.2. Solder3. Screwdriver4. Small diagonal cutters for cutting and stripping small wire5. TweezersMotor Isolation for Kato GP35Carefully remove the loco's shell and weight.To isolate the motor, disconnect the brass strips (motor brushes) from the track pick up ...

KB254 DH165K0 - Function Outputs

The DH165K0 is set up at the factory to control six function outputs. The DH165K0 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 ...
