Q: I have 2 Broadway non-sound F7 DC locos. I bought 2 DH163IP decoders for them. However the decoder is too large to fit into the 8 pin plug provided on the PC board in the loco. A: We recommend a DZ146PS for those locomotives. They will fit in the space available. Don't be confused by the Z designation of this decoder, it is rated at a full 1 amp to run most HO locos but it is small enough to fit in Z scale locos.

Application Note: Walthers/Life-Like F7 H0-Scale steps needed for the DH163D DH123D decoder installation. Remove packing protectors screwed to coupler pockets: Carefully remove shell by spreading sides at side windows: Here's an alternate method for removing the loco shell - our F7 unit had a particularly stubborn shell. In place of the X-acto knives pictured, we recommend toothpicks or something a little safer.. Remove DC Plug (or a DC Printed Circuit Board in this case) from the wiring harness: DC Plug shown removed: Plug DH123D or DH163D decoder to 9 pin wire harness and mount it as shown: Reinstall loco shell.

UT4 Function Control Keys and How they WorkThere are 8 physical keys used to control functions F0-F12 on the UT4 throttle. F1 through F6 and F7-F12 share the same keys.  You will see F1-F6 in black print and F7-F12 in blue print to remind you that you will need to use the SHIFT key to access F7-F12. To use functions F7-F12 you must press and hold down the SHIFT key on the lower left row of the throttle as you press the F7 through F12 keys to activate any functions available on those functions. All the UT4 functions work like other Digitrax throttles. ...

Digitrax SoundFX lets you make your locos sound like the real thing!Remember, your Digitrax SoundFX decoder is ready to run and will operate and generate sound using address 03 with no additional programming.On your Digitrax system, simply select the locomotive's address and the sound will start. On some DCC systems, it is necessary to select the locomotive address AND send a command to start the sounds. When used in conjunction with a separate DCC motor decoder in a single locomotive it is most practical to program both decoders to the same address and operating modes.For a more prototypical railroading experience, ...

I bought 2 DN163I1A and 2 DN163I1B decoders which have brass . My 4 Inter Mountain FT units do not have brass motor contacts (as I found too late on your DN163I1C documentation for F3 units) but rather 2 wires soldered to the original board. Also, the DN163I1A or B can't be fitted in the space provided on the engine not only because the brass contacts on the decoder get in the way but because on the size of the decoder board is a little too big. Will all above render the decoders useless or what should I do? Because ...

Q:  How do I turn off the grade crossing horn sequence when powering up or changing programming? A:  Turn F7 to "off"; it has accidentally been toggled to "on".

The Trix GG-1 is a fine die cast locomotive model which is equipped with a sound decoder. As produced by the Trix factory in Germany, the sound functions are: F0 Normal headlights F1 Bright headlights F2 Cab lights F3 Sound of main relay F4 Low speed switching range (switching acceleration / braking delay off) F5 Bell F6 Horn, continuous blast F7 Sound of pantograph being raised and making contact with the wire F8 Sound of blower motor F9 Sound of switching relays F10 Sound of cab radio F11 Sound of couplers F12 Sound of clickety clack railroad track Digitrax operators ...

The DH165Q1 fits many Atlas, Intermountain, Life-Like & Other factory sound equipped HO locomotives. Installation Instructions - Intermountain F7 example: Removing Locomotive Shell and Disconnecting Lightboard 1. Carefully remove the front coupler and then the locomotive's shell from the frame. Note the orientation for proper reinstallation. 2. Unplug and mark the two track power pickup 2-pin plugs, the motor 2-pin plug and the 6-pin headlight plug(Figure 1) Observe and carefully note the original wire locations! One of the track power plugs and the 2 pin motor plug can be inadvertently swapped when hooking up the new decoder PCB. 3. Unscrew ...

My sound decoder has a capacitor, why do I need a PX112? The capacitor that came with your Digitrax sound decoder is designed to hold up sound operation in the presence of brief power interruptions.  It is not designed to keep the locomotive’s motor and lights running.  Our ears are very sensitive to sound interruptions so, the capacitor on your sound decoder will prevent most of these drop outs on average quality track.  Most people don’t even notice the small pauses in a locomotive’s movement and the small flashes of the lights when the track power is interrupted.  If you ...

This note addresses the installation of an H0-Scale wired decoder into Bachmann Plus ABA F-7s; it calls for using a DH140, which has been retired.  Current decoders such as the DH123 or DH163 or similar wired decoders can be used. Just finished up doing a few HO Bachmann Plus F7's, ABA's to be exact. Thought maybe some of you might be interested in how the DCC conversion went on these.They are an easy conversion!1.  The full stall current for these ranged from 500-700 ma for each loco . I selected Digitrax DH140 for the A units and a DH120 for the B ...

Digitrax decoders have outputs that can control lamps and other on/off devices installed in your locomotive.  These are called functions.  Functions are things like: lamps, sound units, smoke units, etc. All Digitrax decoders are equipped with two or more function outputs that are used to turn functions on and off.Decoder function outputs can be:1.   Leads (wires) attached to the decoder that are used to hook up external functions.  See Table I below for wire color codes used on Digitrax decoders.or2.   Pre-wired function outputs that hook up by just plugging in the decoder. This is the case for decoders that ...

Most customers that use Digitrax command stations use Universal Consisting instead of Advanced Consisting as described here.  With Universal consisting, the consist information is handled by the command station instead of by the decoder.CV19 is the advanced consist address. CV19 also contains data for the direction in which the consist will operate. See the table below to determine what value to program into CV19 CV19 Value Effect on Adv Consist Address Normal Direction of Travel of Advanced Consist 000 Advanced Consist Addressing Disabled N/A 001 - 127 Advanced Consist Addressing Enabled Forward 129 - 255 Advanced Consist Addressing Enabled Reverse When ...

Series 4 decoders like the SDH164k1's will conform to the 10-pin wiring diagram   Function pads for F1 and F2 are located on the SDH164K1 boards on opposite sides by the front headlight. Functions 3 and 4 are located on the 10-pin wire harness, with the Brown wire being the F3 negative and the Yellow wire being the F4 negative.  F3 and F4 functions have a common positive connection to the solder point labeled in the middle of the board.     The common LED sizes used are 3 mm and 5 mm.
