o
If your Atlas sound-equipped locomotive has
Ditch Lights,
the Ditch Lights will turn
Off
in the
Neutral
state
.
o
If your Atlas sound-equipped locomotive has a
Mars Light
,
the
Mars Light
will stop pulsing
and go
Dim
when the locomotive stops
.

Reversing the Locomotive on DCC
This simple operation is done in exactly the same manner as it is with standard locomotives.
−
The direction of motion of your locomotive will change when you press the direction button on your
DCC throttle. To prevent damage to the mechanism of your locomotive, do not press the direction
button until your locomotive has stopped moving.
−
The directional headlights behave as follows:
o
When the locomotive is moving forward, the
Front Headlight
will be
Bright
; when the
locomotive is stopped or moving backwards the
Front Headlight
will be
Dim
.
o
When the locomotive is moving backwards, the
Rear Headlight
will be
Brigh
t; when the
locomotive is Stopped or moving forward, the
Rear Headlight
will be
Dim
(Off
if your loco has
Version 7 firmware and Q1a hardware).
•
Blowing the Horn on DCC
Blow the diesel locomotive
Horn
for short or long blasts – you control the duration. The operation of the
Horn
depends on how your DCC system was designed and configured.
−
If your DCC system has separate
Horn
and
F2
keys,
o
Pressing the
Horn
key will blow the
Horn
only for as long as you are holding the button down.
This behavior is called
momentary
operation.
o
Pressing the
F2
key and releasing it will cause the
Horn
to come on and stay on until you
press
F2
again. This behavior is called
latching
operation.
−
If your DCC system has only an
F2
key, this key may be set at the factory for either
latching
or
momentary
operation, depending on the DCC system. Some DCC systems allow the user to
configure a function key (such as
F2
) for either
latching
or
momentary
operation.
−
If the
Ditch Lights
are
On
, the locomotive is moving forward, and the Horn is blowing (
Horn
or
F2
key
pressed), the Dit
ch Lights
will flash alternately for as long as
F2
is pressed and will continue this
alternate flashing for a short time after you release the
F2
or
Horn
key.

Ringing the Bell on DCC
−
You can turn the
Bell On
and leave it
On
while you operate other functions on the locomotive;
−
Turn the
Bel
l
On
by pressing the
Bell
or
F1
key on your DCC throttle.
−
The Bell will stay on until you do another press of the
Bell
or
F1
key on your DCC throttle (or you
interrupt the track power).
−
Turn the
Bel
l
Off
with a second press of the
Bell
or
F1
key on your DCC throttle.
Note:
When you turn the
Bell Off
, it will continue ringing briefly with less and less volume as the pneumatic
clapper slows down, just like the prototype.
Programming a New DCC Address for Your Locomotive
The decoder in an Atlas Gold Series locomotive comes from the factory set to use the short address “3.” However, in
order to control (independently) several locomotives on the same track at the same time, it is necessary that each
locomotive have a unique DCC address. A convenient choice for the DCC address is the road number printed on the
side of the locomotive’s cab. Frequently, the number on the side of the cab is a 3- or 4-digit number, which is defined
as a
Long (or 4-digit) Address
in DCC.
Most DCC systems allow you to change the DCC address of a locomotive in either of two ways:
•
On a special section of track that is not connected in any way to your layout and is called the
Program Track
.
(In DCC terminology, programming locomotives on the program track is called
Service Mode Programming
.)
