I just acquired my first Trix HO engine with built in DCC/Selectrix. It's a double PA diesel in Union Pacific. DCC options are far and few between, but some still manage to confuse me.
Can anyone explain what following CVs do, description taken from the manual:
CV29: bit 2: 0 - Operation in DCC only with braking section - what's braking section?
CV49: value 0-3 - Pulse width for motor control
CV50: value 0-3 - Rule variant
There is no factory reset code specified, so I'm careful about what I modify. Aside from these the only CVs that are available are acceleration/deceleration rates, long/short address, maximum speed, EMF motor control (I assume this is cruise control) and motor/lighting polarity (I guess it's mainly for DC operation). So as you can see, MTH dcc will run circles around this Trix.
Overall I'm happy with the loco, albeit noisy. There is drawing of speaker in the manual, and chassis have cutout for it, but I'm not sure where I would get decoder for it. There doesn't seem to be a DCC socket anywhere. I must admit I marvel at the hardware design though, unit is made with maintenance in mind - it's really easy to remove the shell with reliable mechanism of attaching it to the frame. No bending of clips and stressing shell like you have to do with Proto 2000 diesels.
Braking section - Marklin and Trix use this system by which if you feed pure DC into the locomotive, it will start slowing down. European modelers use this feature to stop trains automatically at signals.
My suggestion is that you consider using DecoderPro (JMRI) to program your locomotive. It already knows about Trix decoders. I have a Trix hercules Diesel that I programmed via DecoderPro.

Slowly building a layout since 2007!

By experience, I feel that TRIX operates better in a Selectrix system, than in DCC. The guys at Marklin/Trix must learn to much to understand DCC in NMRA terms.
So how does "braking section" applies to DCC, because it's specifically listed for DCC only operation. Is it the feature when the engine is moving and I set Zephyr throttle direction to brake and engine slowly stops?
Oh wow - that's really impressive. I didn't know that can work like that. So you say most decoders have this function? So what does it take to implement such system on home layout, with one train running with priority and than all other obeying signal lights?
(I imagine having all trains being able to work with signal lights they'll need to be controlled via computer program with track sensors - correct?)
