WRITING CVs WITH THE KEYPAD
If you don’t have a DCC system, it is still possible to change CV values in
the range of 112 to 191 with the keypad. Check the MASTER CV LIST for
the specific value you may want to change.
After using the Keypad to change CV values you must turn OFF the LSC II
to allow it to reload the new values and keep all the internals straight.
To enter CV write mode, Press and Hold the two black DOWN ARROW
keys (one on the left and one on the right). The display will show a “C”
and then the number 112, which is the first CV value that can be
configured. Use the up and down keys on the RIGHT side to select the CV
you want to change. Then, using the LEFT side Up/Down keys you switch
the display to show a dash “-“followed by the current CV value.
Using the right side Up/Down keys select the new value for the CV.
Use the left side arrow keys to switch between CV Address and CV value.
Press SAVE to write the new CV value.
To exit the CV mode, press the Keypad On/Off button.
Remember to turn power OFF and back on to restart the LSC II with the
new values.
Note: you cannot change the DCC address of the board using this method.
Use your DCC System to change the board address – which make sense. If
you are using the LSC II without DCC, there is no need to change the
board address.
Why the strange values of 112-191? The LSC II was designed to be used
with NMRA (National Model Railroad Association) compatible DCC
systems. To assure compatibility among different manufactures a range of
memory location was reserved for their use. There are a couple of blocks
of these numbers that start at 1 and go to over 1000. 112 is the start of
