Diesel Sound Decoder with 6 Prime Mover Sound Item #0001909
Thank you for purchasing our advanced DCC diesel 16 bit sound only
decoder. Combined with any non-sound power decoder installed in your
locomotive, and used with your favorite DCC System, our new sound only
decoder will make your model locomotive come to life.
Easy installation - two wire only
Six synchronized diesel prime movers with random associated
locomotive sounds
28 functions (F1 - F28)
2 or 4-digit (1-9999) addressing
Programmable 14, 28, 128 speed steps
Programmable acceleration rate, deceleration rate
Programmable user selectable 22 different horns and 8 bells
Programmable individual sound volumes (16 levels)
Programmable master sound volumes (16 levels)
Supports advanced consisting (CV19)
Supports programming on the main (OPS mode)
Compatible with NMRA DCC standards
Complies with the part 15 of FCC
18mm speaker included
Dimensions: 17.4mm x 17.4mm x 4.0mm
Note- Instead of using CV3 and CV4, the decoder uses CV120 and CV121 as acceleration
and deceleration rates. So you can change its acceleration and deceleration rates without
changing CV3 or CV4 in your power decoder, if you already have these rates tailored for
your locomotives optimum performance.
ADDRESS PROGRAMMING:
The “Sounder” comes with a factory default address of #3, and 28 speed steps. If your
locomotive has a different address, and speed step already programmed into it, place the
locomotive, with decoder and Sounder installed, on your program track and reprogram it to
the address you had originally programmed it to. While it is on the program track, also
reprogram the locomotive to the speed step of your choice, (14-28/128). Since the decoder
does not have a motor driver, you can’t read back its CV.
ADDITIONAL INFORMATION:
The Sounder synchronized diesel sound only decoder should perform well when used with
other brand command systems, and decoders. See your DCC command stations manual
to learn how to program and operate any decoder. For more information about register/
CVs and their functions, please refer to the NMRA DCC Standard & Recommended
practices, RP-9.2.2 available directly from the NMRA or their website at www.nmra.org.
TROUBLE SHOOTING:
This decoder should perform well with all DCC systems. The maximum DCC output should
be less than 15 V. If the locomotive does not respond to commands, it may have lost its
address. Please reprogram the address and program CV19 to 0 (disable consist). If it
responds slowly, you should clear its momentum by reprogramming CV120 and CV121 to
zero. You should also clean the track to improve electrical pickup. Read your DCC system
manual to learn how to program and operate the decoder. Whenever the decoder doesn’t
work please use the program track to program CV# 125 with value 1 to restore the decoder
to factory settings. This should bring the decoder to life with address #3.
