does exist, the blue cable remains unused. When connected to the blue cable, the bulbs shine
somewhat brighter and, in addition, the direction-dependent lighting then also works in normal DC
operation. Which option you choose depends on the design of the locomotive.
For the connection of the LEDs, note that the blue cable is the positive pole (anode side of the LED)
and the function output is the negative pole (cathode side of the LED). The voltage at the function
output is approx. 16 V. Please do not forget the necessary protective resistor.
Now connect outputs C and D (if your locomotive has further functions):
•
function output C (green cable) to another locomotive function.
•
function output D (purple cable) to another locomotive function.

Installing the LE1025 via interface plug NEM652 (Abb. 2, p.4)
These decoders come with a NEM652 / NMRA RP-9.1.1 medium plug. This plug makes the
installation of these decoders very simple.
To install the decoder simply remove the dummy plug in your locomotive and install the decoder
plug. To ensure the headlights work correctly you must align the plug properly. Pin 1 of the plug
connects to the orange wire. Ensure this is aligned to Pin 1 of the locomotive. If the plug is installed
wrong way round the lights will not work.
When installing the plug ensure that the pins are not bent or broken.

Testing the installation
Place the locomotive on the programming track (without its housing) and read the address. The
decoder is programmed ex-works to the address 03. If you have connected the decoder correctly
thus far, you should now be able to read the address. If you are not able to do so, it is possible that
you have made a mistake when connecting the cables. Do not subject the locomotive to full running
