How to Install Sound in the AeroTrain
Using Con-Cor's Special DCC Ready Coach
Car
This special
version of the Con-Cor HO AeroTrain Coach car is factory modified and
ready to be fitted with any brand of DCC Sound Decoder you choose. Note:
The sound decoder is sold separately and can be found at Factory Direct
Trains. We recommend MRC's Sounder with Sound and
Motor Control 1800.
This car includes a special extra long extender harness to bridge
between the NMRA 8-pin plug installed on the AeroTrain Locomotive PCB
board and into the DCC ready Coach.
To install your sound decoder into the coach, follow these simple
steps:
Photo # 27 Photo #28
Photo #27 - Remove the body shell from the powered locomotive of the
AeroTrain. DO NOT use any metal or plastic tools. Use wooden skewers as
seen in the photos. If you use metal or plastic tools you will mar the
finish of the model or gouge the plastic, ruining your model.
Photo #28 - Once the body is off the chassis, set it aside.
Photo #30 Photo #32
Photo #30 - Carefully remove the Analog plug. Do not lose it. Put it in
a safe place. You will need it again if you plan to operate your AeroTain
in the DC mode.
Photo #32 - Here is the Wiring harness include for the Sound car. It is
actually an "Extension" cord like you would use for an electrical item in
your home. The difference here is that it is much smaller, uses eight
wires and is used for DCC. (Digital Command Control).

Photo #33 - Plug the 8-pin male end of the Wiring Harness into the
female plug of the locomotive of the AeroTrain. This is located behind the
engineers' cab on the printed circuit board.
Photo #34 - Once you are done, the Wiring Harness should look like
this:
Photo #37 Photo #38
Photo #37 - Now thread the Wiring harness through the opening of the
diaphragm of the body shell.
Photo #38 - Snap the body shell back onto the locomotive's chassis. The
Wiring harness will extend out of the back end of the locomotive as
pictured.

Photo #35 - Here is a view of the Sound car. Note that it looks exactly
like any other coach in your set. The difference is in the interior of the
coach
Photo #36 - Notice the seat backs have been removed to accommodate the
MRC speaker from their #1000 Sound Decoder. The car was also designed with
pre-drilled holes in the floor so the sound can escape, giving you optimum
sound quality. While the MRC Brand Sound Decoder is used in these
instructions, you have the option of using whichever DCC Sound decoder you
choose. If your speaker is too large for the sound car, you can simply
trim off more of the seat backs.

Photo #39 - Thread the Wiring harness through the opening of the coach
diaphragm.
Photo #40 - The same wooden skewer should be used to separate the wires
in front of the coach chassis to make threading the Wiring Harness easier.
Be careful, these wires are thin and can be broken off of their solder
points if you are too rough with them.

Photo #42 - Once the wiring harness is threaded through, it should look
like this:
Photo #31
Photo #31 - The MRC #1000 Sound Decoder is pictured although we
recommend the MRC #1800. Note that the
speaker is attached and the whole unit is "Plug-n-Play".
Photo #43 Photo #44
Photo #43 - Now, plug the Sound Decoder into the Wiring Harness. Again,
the 8-pin male connector to the female 8-pin connector of the Wiring
Harness.
Photo #45 Photo #46
Photos #44 - #45 - #46 - Now remove the P3 spade cover on the Wiring
harness and place the Green wire from the decoder through the insulated
opening on the Wiring Harness marked P3. Once you are finished, replace
the spade cover. This procedure is for those using full DCC (Digital
Command Control) and allows you to access the "Crossing" light feature of
the AeroTrain. Please refer to the instructions included with your set for
more information.
Photo #47 Photo #29
Photo #47 - Now, place the speaker and the decoder Printed Circuit
Board into the chassis of the coach.
Photo #29 - Snap the body back onto the coach chassis, connect the unit
to the locomotive of the AeroTrain. Now you are ready to operate in DCC
with motor control and synchronized sound.
DC users also get primemover sounds with this configuration. To
activate horn, bell and other sounds, simply purchase the MRC BlackBox,
available at Factory Direct Trains.
