Locomotive decoder LE063XF 2

LE063XF Universal DCC Decoder

The LE063XF N-scale DCC decoder can be used with all popular

NMRA-compliant DCC systems. This decoder is in full conformance

with all NMRA Standards and Recommended Practices and has been

augmented to work well with all major DCC systems on the market.

Although the LE063XF decoder has a low price, it is packed with all the

features that you expect in a high-end decoder:

•Directional or independent lighting (both of which can be dimmed

using DCC function keys),

•Supports both short (2-digit) and long (4-digit) addressing,

•Advanced consist control (operating and controlling several

locomotives as if they were a single entity by sending speed and

direction commands to a common consist address that is stored in

the decoder of every locomotive in the consist),

•Operations mode programming (programming on the main line),

•

Full support for all the various motor speed-step modes, including

the 128 speed-step mode.

Many characteristics of the LE063XF decoder can be programmed to

customize the decoder to its locomotive. Please read The Configuration

Variables and their Definitions section for details on the configuration

variables supported by the LE063XF. The LE063XF decoder supports

all forms of programming described in NMRA Recommended Practice

9.2.3, including the user friendly direct CV (Configuration Variable)

programming mode and operations mode programming. For example,

you can operate the decoder with the factory-default speed curve, or

you may specify your own customized speed curve. You can also set

which end of the locomotive is to be the forward end. You can even

decide whether or not you want to be able to operate the locomotive on

conventional DC layouts. If your DCC system supports operations

mode programming, you can change the values of all CVs (except for

the locomotive’s 2- and 4-digit addresses in CV1, CV17, and CV18)

while the locomotive is on the main line.

Preparing to Install the LE063XF Decoder

Before installing the LE063XF decoder in your locomotive, it is

necessary to test (and adjust, if necessary) the locomotive for proper

operation on conventional DC power. Replace any worn out parts, such

as brushes. Also clean any dirt or oxidation from the wheels and

pickups to in order to insure that electrical contact is good. Now is also

a good time to lubricate your locomotive. A locomotive that runs well

Locomotive decoder LE063XF

Atlas Model Railroad Co., Inc.

under conventional DC will also run exceptionally well under DCC.

The LE063XF decoder is quite small and will fit into the B23-7, B30-7,

B36-7, Dash 8-40B, GP-38, DCC-ready GP-40, GP-40-2, DCC-ready

SD-7, DCC-ready SD-9, SD-35, Train Master, and U25B locomotives.

Precautions to Take When Installing the Decoder:

Although the LE063XF decoder has many internal safeguards to prevent

damage, you must not allow any metal part of the locomotive to touch

surface components of the decoder other than the pickup pads on the

decoder that connect to the wheel-sets, the headlights, and the motor.

Any contact to other parts of the decoder can cause a direct

internal short circuit and destroy the DCC decoder.

The LE063XF decoder is not completely protected against static

electricity and has sensitive electronic parts. When installing this

decoder in your N scale locomotive, it is recommended that you wear a

grounded anti-static wrist strap. Also be careful in handling the decoder,

especially in the area around the top rear part of the decoder (the area

where the microprocessor is located).

The LE063XF comes with two LED headlights already

installed. The light outputs of this decoder are designed

only to drive these LEDs. The Atlas warranty is void if these

LEDs are removed from the LE063XF circuit board.

Locomotive decoder LE063XF 4

Step by Step Installation

In the following steps, please refer to the instructions provided with your

Atlas locomotive.

1) Remove the locomotive's body shell and fuel tank. Use care so as

not to damage any of the fragile parts.

2) Loosen the two screws that hold the frame together; these screws

are located at the front and rear of the frame.

3) Carefully remove the lighting control circuit board, which is located

at the top of the frame.

4) Place the decoder between the two halves of the frame so that the

two motor contact pads are at the bottom of the decoder and will

press firmly against the two copper contact strips from the motor

when the decoder installation has been completed. In the

photograph of the bottom of the LE063XF decoder on the first page,

these motor contact pads are the two rectangles in the narrow

center portion of the circuit board.

5) Carefully press the two frame halves together, with the sides of the

decoder inserted into the notches in the two halves of the frame.

Some pressure is needed to press the two frame halves together.

This pressure fit insures good electrical contact between the frame

and the decoder.

6) Tighten the two screws that hold the locomotive frame together.

7) Carefully check to make sure that the motor contact strips are not

touching either half of the frame. It is necessary to look down from

the top through the frame cutouts in order to check for such

unwanted shorts,

There must be NO electrical contact between the motor

contacts and any part of the frame

Place the locomotive (without its body shell) on your DCC programming

track and read back the locomotive's address from the decoder. If the

decoder is properly installed, you will be able to read back the factory

pre-set address 03. If your DCC system does not support reading

decoder properties, observe carefully the decoder's behavior while on

the isolated programming track. Each time you try to program the

decoder you can see the acknowledgement that is sent by the decoder

in the form of a brief and minor jerk of the locomotive. A successful

acknowledgement means that you have installed the decoder correctly.

Remove the locomotive from the programming track and, if necessary,

correct any installation errors. Once you have successfully programmed

the decoder, reinstall the body shell and retest the locomotive on the

programming track. If this test is successful, the locomotive is ready to

use.

Programming the LE063XF Decoder

The LE063XF decoder supports all forms of both service mode

(programming on an isolated programming track) and operations mode

programming (programming on the main line). Using any of these

programming methods, many features (such as the locomotive's

address, acceleration, and configuration) can be customized to the

individual locomotive in which the decoder is installed. These

customized properties will be saved in non-volatile memory locations on

the decoder so that they will retain their values even after power has

been removed. All parameter values are set electronically, which means

that the locomotive does not need to be opened again after the decoder

has been installed in order to read or modify the values of these so-

called Configuration Variables (CVs). The LE063XF decoder has a total

of 128 CVs. Not all of them are used at this time because many have

been reserved for future use.

Any NMRA-compliant DCC Command Station, such as the Atlas Master

Commander, can be used to program the LE063XF decoder. With

several entry-level systems, only CV #1 (the locomotive address) can be

set unless you use a separate DCC programmer. More advanced DCC

systems, including the Atlas Commander, support the ability to set many

more CVs. The LE063XF decoder supports all programming modes

and can be programmed by all NMRA-compliant DCC systems. The

locomotive’s 2- and 4-digit addresses in CV1, CV17, and CV18

connot be programmed in operations mode. Instructions for reading

and writing CVs are given in the user manual of your DCC system.

Note: In order for newly programmed CV values to take effect after

service mode programming, the decoder must go through a power

reset. If your DCC command station does not support automatic

power reset, simply rock the locomotive off the track after

programming.

Configuration Variables and their Definitions

The LE063XF decoder supports a full range of features, which are

activated by setting Configuration Variables. All CVs are numbered.

These numbers are used during programming and are identical for all

decoders that conform to NMRA standards, regardless of the decoder

manufacturer. The following table lists the CVs supported in the

LE063XF decoder. Both CV numbers and Register numbers are

provided for cross-reference.

Some CVs (such as CV29) have specific meanings for each bit. In

order to conform to the NMRA convention for bit numbering, the CV bit

assignments shown in this table use the bit-numbering scheme of 0 to 7.
