21.1. Programming long addresses

As described in chapter 9.2. the long address is split into two CVs.
The byte with the higher value of the address is in CV 17. This
byte determines the range in which the extended address will be
located. For instance, if you enter the value 192 in CV 17 then the
extended address may be between 0 and 255. If 193 is written
into CV 17 then the extended address will be between 256 and
511. You can continue this up to addresses with values of 9984
and 10239. The possible values are shown in figure 31.

21.1.1. Write address

To programm a long address you first of all need to calculate the
values for CV 17 and CV 18 and then programm it. Please note
that it is not possible to programm addresses via the programming
mode "POM".
To programm the long address proceed as follows:
• Zuerst legen Sie die gewünschte Adresse fest, zum Beispiel 4007.
First you determine the desired address, for instance 4007.
Then you look for the appropriate address range in Fig. 31. The
value to be entered into CV 17 can be found in the column on the
right. In our example, it is 207.
The value for CV 18 is established as follows:
desired address
minus first address in the address range -
===============================
equals value for CV 18
• 167 is therefore the value to be entered in CV 18. Thus you de-
coder is now programmed to address 4007.

21.1.2. Read out address

If you wish to read out a loco address please read the values of CV
17 and CV 18 one after another and proceed then in reverse order:
Let's assume you have read:
CV 17 = 196; CV 18 = 147. Look up the corresponding address
range in Fig. 31. The first possible address within this range is
1024. Then you have to add the value from CV 18 and you arrive
at the locomotive address:
