FULL CV LISTING GUIDE
RAILS CONNECT DCC DECODERS are designed to give silky-smooth running "out of the box" - with advanced brown-out
protection and fully self-adjusting back-EMF as standard.
BEFORE you install your new RAILS CONNECT decoder.
Please test run your locomotive on DC if possible. If it does not run well, even if it is new, make sure that wheels & pickups
are cleaned. If needed, adjust the pickups so that they contact the wheels reliably. New loco's are usually pre-oiled but if it
has not been used for a long time, remove the old oil and oil again with tiny drops of plastic-safe oil.
INSTALLING your new RAILS CONNECT DCC decoder.
•
Remove the DCC blanking plug from the locomotive socket.
•
Insert the decoder. Note that 21 pin decoders install with the PCB side down and you should press down firmly but
evenly so the pins engage evenly. 6 pin decoders are installed with the RAILS logo on top and 8 -pin direct decoders
are installed correctly when the #1 pin of the socket is at the same end as the S in the RAILS logo. For 8 -pin harness
decoders, the number 1 pin is the orange wire on the 8 -pin plug.
BEFORE you attempt to run your locomotive on the layout.
After installation, always place your loco onto the programming track first. This is always a good idea as the lower power of
the program track will not cause damage if the loco wiring is faulty. If your decoder won't respond on the programming
track, check the installation.
ADDRESS your new RAILS CONNECT DCC decoder.
The default address is 3. RAILS CONNECT decoders can be set at any address between 1 and 9999. Use your controller
instructions.
RESET and additional setup or adjustment of your decoder.
Set CV8 to 8 to restore ex -factory defaults. Your decoder has a huge range of features. The following pages detail the
extended range of CV settings that can be adjusted on your decoder.

The value entered into CV 10 directly correlates to the speed step at which it will cut out. That is to say if you wish to disable BEMF at speed steps above speed step 50 enter a value of 50 into CV 10.
