22 Information SET-02
Within a decoder there is a storage location for each feature. A
value is stored in each storage location. These storage locations are
comparable to the cards of a card index box. In each decoder you
find such a "card index box". On each "card" a feature of the
locomotive decoder is written down, for example on "card" number 1
the locomotive address, on "card" number 3 the acceleration rate.
That means one card for each feature. Depending on the number of
features available in this decoder, the size of the "index card box"
varies. On each "card" you will find a numerical value, the general
range of values of such a card is 0 to 255.
Since you can alter these numerical values on the index cards (in
these storage locations) at any time, they are often called variables.
These variables are used to determine features, you use them to
configure , and that is how the term " Configuration Variable ",
abbreviated to CV, developed (in the US). From now on we will no
longer talk about index card, but instead we shall use the correct
term CV. The concept of the CV will be used to explain the features
or operations of the decoder.
Which CV contains which feature is standardized. CV1, for
example, is always the address of the locomotive, CV3 is always
the acceleration rate and CV4 the braking or deceleration rate.
Information on which CVs are supported by a decoder and which
features can be set with them, can be found in the decoder's manual
which is available from your model railroad dealer. You can also get
these documents by sending LSSAE / pre-paid envelope to Lenz
Elektronik GmbH or from our WWW site.
Whether all possible figures from the range of values 0 to 255 are
available for use, depends on the feature. For the feature "Basic
address", CV1, only the range of values from 1 to 99 is available.
For CV53 (dimming of function outputs), however, the whole range of
values from 0 to 255 is permitted.
In addition to this, there are "cards" on which the entered numerical
value is written differently in order to make it easier to deal with. This
other presentation of the number we call
binary presentation . Here
the numerical value is not presented using the figures
0,1,2,3,4,5,6,7,8,9, but using only the figures 0 and 1.
It is easier to picture 8 switches in the relevant CVs that can be
switched on and off. These switches we call "bits". If the switch is
switched on, we say "the bit is set" or " the bit is 1", if the switch is
switched off, we say "the bit is deleted" or "the bit is 0".
