LGB on board decoder ME014385 by Massoth

No buffers were hurt at this sign

I have a couple of yellow Cargo Sprinters....they came with onboard decoders which I understand were made by Massoth specially, and not available to buy individually.

Annoyingly, the lights ( headlights and cab light ) are non directional.....on or off. With just another mini ct connector, they could have been directional.

I've been looking for a diagram of the board, I've found this image from another thread where the question was posed 'is this a susi sound output' ( answer no..but massoth susi modules can be made to accept the lgb data format )

So, starting at the top right, the ct connectors are: PLUG ( with red/black cables ), LI-R ( rear light? ), unknown bottom right corner??, SW or is it MS?, above it is SND sound,; crossing to bottom left, that's F1, screw, then LI-F ( front Light ), then LI-F again, then across to the plug with the black and brown cables LI-0. At the lh middle are two pins for smoke.

The lights in the cargo sprinter are in the LI-0 socket. With some work I can split the cab light from the headlight board...so headlight boards fit in LI-F and the cab light in LI-0

Have I got this right?

Its not SUSI, but almost :) They call is "LGB Bus". eMotion S decoders should be able to handle the data presented, however you will probably need a axle sensor too.

You should be able to make the lights directions by CV settings. Now where did I put the CV list for these decoders....

Guys, thanks for the image and the cv's....

I've just been to order some 2 pole ct plugs with leads to make separate outputs for cab and headlights, darn it, they're out of stock. But hey...a 4 pack....just the job.
I may add some red tail lights

Now, the multi purpose socket at the top rhs....is this for power outlets at each end of a loco..not used in the cargosprinter but used in the image I borrowed?

Thanks, just so this thread is more searchable..the cargo sprinter is 20970, and I have seen images of similar decoders ME014320 and ME014390 which probably have slightly different firmware or hardware.

I think I've read somewhere that fitting a power buffer to this decoder is difficult, as ground isn't available on a pinout, thus requiring soldering direct to the board. I may fit extra pickups to the trailing bogie ( and a weight ) as at low speeds a single cargo sprinter stalls on some R3 points.

Greg,
It conforms to signal levels etc., but 'speaks' a slightly different 'dialect'..
 
OK, so how does that "jive" with Massoth's statement that you can connect an eMotion decoder? Is there a setting for an "alternate" comman set?

I've been bashing my head in with an eMotion decoder for the last month, and have gone through the CV's... I did not see anything pertaining to this.

Is there any documentation about this "difference" anywhere? Seems very strange that with Massoth making the early LGB decoders that they would change anything... perhaps not support all features, but change?

Clearly anything is possible, but why would anyone go to the extra effort to program differences? It would most likely take extra programming of the compatible sound decoder too.

Update: (after more careful research :think: )

There are INDEED bits in the Massoth eMotion decoder, bit 4 of CV49 that is between Massoth and SUSI bus AND bit 7 that is between SUSI and Marklin... wow... so this is why the eMotion can work with it... what a mess... but compatible ha ha!

The best thing about a standard is it enhances compatibility... messing with it with small variations is really not good... I suspect the real reasons here are rooted in early development and a desire to force the customer to buy one manufacturer's product.

what a great help,thank you!
I will switch the decoder (the two motor version from the above sketch) from a Mallet to a rhaetian crocodile.
What is the purpose of F1? It cannot be light because it was left blank.
Gearbox 1 is the front of the locomotive where the driver stands?

I found the manual, but a few questions remain... (see above)

the two motors are running at a different speed. I found a sentence that says: load regulation CV52 and CV53 take care, but in my list these parameters handle rear and front light.
The decoder has 2 motor exits, so there should/could be a possibility to improve only one motor.

CV 5 top speed could be your friend here, value of 1-250 top being track voltage. Default in my manual is 200 so try a bit less on one say 180 and see how that goes. Other cv’s tyat may help
CV 2 starting voltage
CV 3 acceleration time
Just remember to note on some paper or a notes book what they were before you start playing around with them.
 
It sounds like one motor is 'tired' (worn) or one has been changed..

The best way to fix this is to buy two new motors, and swap them.

You can then use the older motors, as spares for single motor locks.

I am led to believe that Buhler changed the design of the motor, a few years back.
The newer model is more efficient, so will behave differently to an older model.
That is why I suggest changing both motors.
