DCC Features:
The decoder provided with the GenesisTM Challenger
Locomotive will operate with any NMRA compatible DCC
system. The default setting is address 3. The decoder is rated
at 2 amps and will support either 2 or 4 digit addresses. The
decoder functions are fully programmable by the adjustment
of CVs. A CV table is included in the operating instructions.
Either 14 speed steps or 28/128 speed steps are supported by
this system. Available accessory and sound functions are as
follows:
• Directional Lighting • Bell
• Whistle • Air Release
• Coupling • Brake Squeal
• Conductor’s Voice • Fire Box Door
• Sound On/Off • Sand Release
• Water Injector • Blower Hiss
• Cylinder Cock/Flange squeal
In addition to Function Ø (Directional lighting) there are
twelve additional sound functions to allow the operator to
capture the full range of unique sounds found on an operating
steam locomotive. You can now fully immerse yourself in the
complexities of prototype operation and add a new level of
realism to your railroading experience.
