Auto Coupler Sequence Threshold Value: CV151:
CV151 controls the threshold at which coupler and brake sounds are
automatically played when the locomotive direction changes and func-
tion 3 is enabled. CV151 has a range of 0-60.
Loading Other Sound Projects in your SDH187MT:
Decoder sounds can be re-loaded or customized using a Digitrax SFX
programmer and your computer with the SoundLoader II software. Both
the software and a number of alternate Sound Project files are available
from the Digitrax Sound Depot web site. It takes only a few minutes to
download the new sounds to your decoder.
Prior SFXv1 and v2 Sound Projects can be loaded into SFXv3 decoders if
sized to fit in sound memory. SFXv3 projects may run on older SFXv1/v2
decoders with decreased functionality.
For example, earlier v1/2 decoders may be limited to 3 or 4 sound chan-
nels, whereas SDH187MT decoders can run new SFXv3 sound projects
with up to 4 simultaneous channels in the scheme.
The additional channels allow e.g. V3 steam sound schemes to overlap
near and far-side steam sounds for more realistic steam scheme opera-
tions.
SoundFXv3 DC Operation Mode:
1.
Digitrax SoundFX v3 decoders will operate on smooth DC power if
CV29 is default value 06, allowing Analog Mode conversion.
2. Sound/motor will not start until about 6VDC on the track.
3. It is not practical to Consist/MU decoder equipped locomotives with
non-decoder equipped locomotives, since they will not operate at
same speed on shared track DC power.
SDH187MT Troubleshooting:
If sound does not start in the decoder when on powered track:
1.
Make sure you have selected the locomotive address on a throttle.
The sound will not startup and run unless the locomotive is ad-
dressed by the system.
2. Check your installation to make sure the decoder is installed
properly.
