Sound Decoder Installation

I don't understand what the white cam lead gets hooked up to. Some model steam locomotives are equipped with, or can be equipped with, a cam arrangement which coordinates the sound to the rotation of the drivers creating chuffing. As the wheels turn, a switch opens and closes, operating the chuff sound produced by the sound decoder. The white wire goes from the decoder to a microswitch which is operated by a cam that is mounted on the axle of one of the drivers. In operation, when the white wire senses the DCC track signal, it operates the chuff sound ...

The SoundBug track connections are shown below: The SoundBug is assigned the same address as the mobile decoder, with the only shared CV's being the address (CV01), the Configuration Register (CV29), and the headlight and momentum settings. Sound projects loaded into this decoder may be operated independently of any other DCC motor or function decoder. If another non-Sound FX compatible DCC decoder is connected to the track leads then CV readback of SFX004 Sound CV's and PR3 SoundTest modes may not be possible. Note that it is always possible to Write CV values using Operations mode or a Service Mode ...

Note the SFX006 is identical.  These instructions pertain to both Soundbugs.   1) Identify the correct orientation and mounting side of the DH165 series Decoder with SFX004 Soundbug Socket to plug this sound module into. There is text saying "SFX here" etc,. The SFX004 must only be mounted from the correct side and orientation, for each of the DH165 host decoders. 2) With correct orientation noted from step 1, align the dual row of SFX004 connector pins to the matching holes in the DH165 host PCB. Apply gentle and firm pressure behind the SFX004 connector to engage the pins until ...

Wired Mobile Decoder with SoundFX™+Accessory type functions for most HO scale Locomotives.

Wired Mobile Decoder with SoundFX™+Accessory type functions for most HO scale Locomotives. 1. Connect the Red and Black track wires from the 7 connector Track and Function leads to the locomotive track power connections. 2. Connect the function leads that are to be used from the 7 conductor Track and Function wire set. Note that to be able to readback Sound FX CV's a combination of function lead loads of at least 60mA at 12volts should be connected to these function leads. Insulate the unused function leads so they cannot short to the locomotive frame or track power. 3. Mount ...

SDN144K0A installation question about the capacitorIs the 100microF capacitor needed? Or is it only for use in the Kato E8B unit when both LEDs are removed? If it is part of the installation, what size hole doesit need for mounting? The 100uF capacitor is required for all installations.  The capacitor provides keep alive voltage to the decoder.  This is important when the locomotive runs over a section of dirty track or is traveling through a non powered (insul-frog) turnout.  On non-sound equipped locomotives, typically you will not see the locomotive hesitate or lose power when it encounters dirty track.  With ...

I would like to re-power two old Athearn Alco PAs and sandwich a dummy PB in between. I would like to know if is possible /practical to install a sound module in the dummy unit. Actually, there's probably enough room to fit something in the A-units, but you could install sound into the B-unit if there is a way for track power to reach the sound unit. Consider the SoundBug SFX006 which replaces the SFX004): The speaker diameter is 28mm, or just a bit larger than an inch. You will need to fit the speaker into a baffle and the ...
