LokSoundXL User Manual V2.1 05/2002

Adjusting CV’s using DCC systems

5.3 Adjusting CVs

After having been introduced to the effects controlled

by CVs in paragraph 5.1 and 5.2 we now need to

clarify how to set the CVs. There are 3 possibilities:

•With a PC and LokProgrammer

•With a DCC compatible digital command station

(e.g. Intellibox, Lenz digital plus)

•With Märklin® 6021

Depending on the product used the procedure varies.

5.3.1 Using LokProgrammer

The LokProgrammer by ESU electronic solutions ulm

GmbH offers the easiest method to modify CVs of all

LokSound decoders: with a click of the mouse using

MS-Windows®. The PC helps you to find the various

CV numbers and values. With the LokProgrammer

you can also modify the sound effects of LokSoundXL

decoders and you may create your own sound effects.

You may purchase the LokProgrammer at Model Train

outlets complete with detailed operating instructions.

5.3.2 Using DCC systems

There is no "one fits all" instruction for programming

of CVs with various DCC systems. There are too many

differences between the popular DCC systems.

Whenever possible you should use the DCC direct mode

(CV programming by setting individual bytes with

Uhlenbrock) or DCC paged mode.

Refer to chapter 9 "programming" of the user manual

for the Intellibox. In particular read chapter 9.5

"programming of DCC decoders" very carefully.

Programming should be done in the "CV-programming

byte-wise" mode.

Lenz digital plus

There are various software versions available of the

Lenz digital plus command station. You need firmware

version 2.3 or higher in order to program LokSoundXL

decoders. Contact Lenz for more details regarding

upgrades of older versions.

Use "paged CV" mode for programming.

Depending on the firmware version the "CV

mode" might cause problems.

Older command stations such as "Digital plus", "Lenz

compact" and "Arnold Digital" create another

phenomenon:

•Programming is not possible. The Lenz command

station displays "err02", the Arnold command

station "short circuit":

This is caused by the overload protection of the digital

system, which is very sensitive. The LokSoundXL

decoder with the built in audio amplifier uses a higher

current than other decoders and thus activates the

overload protection of the systems. To rectify this,

solder a resistor with 47 ohm (0,5 Watt) in one of the

two wires, connecting the digital command station

with the programming track. See figure 13.

5.3.3 Using Märklin® 6021

With the Märklin® command station you cannot

modify standard CVs as it does not comply with the

NMRA DCC standards. However, the most important

CVs of LokSoundXL decoders may be changed with a

specific programming mode, described as follows:

You cannot program the 6021 with the CV concept

because only values from 01 to 80 may be entered

with this command station. That's why we call values,

which may be modified with the 6021 "registers". Each

of the 64 registers responds to a DCC standard CV.

Figure 14 shows a list of the register numbers and

their CV numbers.

If you want to change a certain CV you have to look

up the register number first in figure 14 and then

modify it.

Many CVs have three digit values, however, the 6021

only allows a two digit input. The LokSoundXL decoder

overcomes this problem by multiplying the entered

value with a factor. The result will be memorized

internally. See figure 14for the appropriate multiplier.

That means that not all functions of the LokSoundXL

decoder may be adjusted with Märklin® command

stations.
