KB295: Using the SFX004 SoundBug with Other Decoders

This article was last updated on Jan. 17, 2012, 5 p.m. | Print Article | Leave Feedback

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 programming track, even if CV Read is inoperative.

If the connected function loads are insufficient for CV readback with a PR3 or an incompatible DCC decoder is also connected, it is still possible to download a complete sound project by using the large green "program project" icon in the SoundLoader program.
