How to check address

Please connect feeder wire and DC power supply as the following.

We are preparing functions to use when you do not know the address of the locomotive on the track. You can check by selecting the item called Check LocAddr.

Press ENTER to start CV reading.

The following display will be displayed during reading. The locomotive will tremble continuously irregularly but please wait for about 10 seconds without being surprised. In case of error, an error is displayed and cancels reading of locomotive address. Please confirm the contact of the railroad track and try again. In addition, there are also decoders and vehicles that can not be read by all means, so resignation is crucial at that time.

You can find this decoder address is 3 with short address.

Configuration step of Nucky's signal decoder

The Japanese type traffic light machine made by Nucky is pretty tough to configure its address. Using DSbluebox, you can easily set the accessory address in 5 address slots at once. A slot containing 0 is not written. Also, with this function, only address is set. For other settings, use the normal CV writing function. Also, since traffic light consumes almost no current, CV reading can not be performed. Watching the LED blink, I judge whether it was written.
