The official word on MRC Black Box and BLI Blueline engines.

Model Railroader General Discussion (Model Railroader)

The MRC Black box is a single address DCC system.

It will only run engine #3.

The Blueline engines will run with the Black Box, AS LONG AS THERE IS A DCC DECODER INSTALLED.

The Black Box can reprogram any engine to #3 by pressing
F, 9, 9. Unfortunately, this only works with Blueline software Version 7 or later.

So, for older Blueline engines as long as there is a decoder installed and the engine is not changed from its default address #3, it will work.

For newer engines as long as there is a decoder installed , if it is programmed to something other than #3, you can hit F,9,9 and reprogram to #3, then cycle the power and it will run.

Bob:

Is there an easy way to tell which Blueline engines are early or later ? Serial numbers or something like that?

Thanks

Why would anyone want a DCC system that can run only one engine anyway?

By the way Mr Grubba, you have a great repair staff. Larry, Matt and others are great assets for your company.

may as well go back to block control if you do that. Gives you all the bells and whistles DCC does tho

If it reset everything to factory default, not just the address, it might be a handy tool to correct poorly programmed decoders. Other than that, it sounds pretty pointless.
