How do I determine the higher and the lower-order byte of a 4-
digit locomotive address?
First, determine the desired address, e.g. 1234.
Then, select the relevant "range of addresses" from the "Table of
extended locomotive addresses" further below. In the column to
the right, next to the range of addresses, you will find the value
that needs to be entered in CV17. In our example we use 196.
To establish the required value for CV18, calculate as follows:
Desired address
In
numbers:
1234
minus
First address in established range
of addresses
-
1024
equals
Value for CV18
=
210
In this case, 210 is the value that needs to be entered in CV18.
Your decoder is now programmed to address 1234.
When reading out the address of a locomotive, read CV17 and
then CV18 and proceed further in reverse order:
Let us assume that you have read out the following: CV17 = 228;
CV18 = 145. First, look at column CV17 and establish the
respective range of addresses. The first possible address of this
range is 9216.
Now all you have to do is add the value from CV18 and you will
know the locomotive address:
9216
1024
145
+
210
9361
or in order to quote the example of the
locomotive address 1234 again:
=
1234
