KB720 Trouble reading CV values with SFX064D

If you have trouble reading back CV's on the programming track, this may be due to insufficient current draw on the SFX064D function leads. You can always just re-program the CV value into a CV to get the desired results, even though reading CVs does not work. OPs mode is recommended for programming all CVs except CV01, CV17 & CV18 (2 digit and 4 digit addresses). If a second DCC decoder is present that is not Sound FX compatible then correct readback of CV data is not possible, since the NMRA CV readback was not designed for multiple decoder readback.

KB129 Recommendation For Small Starter Layout

I have a 4x8 H0 scale layout.  I'm 13 years old and REALLY thinking about switching to DCC, I need to know really fast because I want to ask my parents to get it for Christmas.You wouldn't know by looking at those who edit the Tech Support Depot, but there actually was a time when we too were thirteen, and just starting out in model railroading.  In many ways, we still are thirteen years old; we just can't move as fast.  Consider this photograph from our youth: This little bit of ancient model railroad history dates back to the 1950's, ...

KB258 DH165L0 - Soundbug Installation

Installation of the SFX004 SoundBug 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 ...

KB727 SFX064D Sound Decoder Installation Instructions

1) Connect the Red and Black track wires from the 9 pin Track and Function harness to the locomotive track power connections.2) Connect the function leads that are to be used from the 9pin Track and Function harness. 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 the 28mm speaker attached to the 10pin sound feature harness in an appropriate sound enclosure. Be ...

KB717 Using SFX064D with other DCC Decoders

The sound project loaded into this decoder can 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 SFX064D Sound CV's and PR2/PR3 SoundTest modes may not be possible. Note that it is always possible to Write CV values using Operations mode or a Service Mode programming track, even if CV Read is inoperative.If the connected function loads are insufficient for CV readback or an incompatible DCC decoder is also connected, it is still possible to download a complete sound project by ...

KB589 SDN144K0A Installation Questions-Capacitor Installation

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 ...

KB501 Soundbug Q & A

Q:  What is the white wire for on the SoundBug? A:  The white wire is used on conjunction with a driver cam for steam sound synchronization. Q: What type/size loco does "generic" steam sound represent? A:  This sound was based on recordings of Union Pacific 3985, a 4-6-6-4 "Challenger" type.  Q:  Does the Sound bug come with an oval speaker to fit in the shell of the older model GPs or SDs that do not have space in the fuel tank. A:  The SoundBug comes with a 28mm round speaker but others may be substituted. The included-speaker is rated at ...
