Hi guys

Those who regularly read my threads know that I had a lot of problems with my rails used to detect trains by wheels on locos and wagons.

With the help of Lasse (Danlake) first and Peter (PMPeter) second, I was able to solve the problems.

And I thank them for that.

I ground the ends of the rails (about 64-66 rails) .

It took time and as usual everything worked... one day.

This afternoon... again a problem three S88 diodes light up on the layout of the cs2.

On the TCO these 3 blocks are declared "occupied" and no coaches or freight cars or locomotives are in the blocks.

Under the table in some places the wires of the S88 are even coated with aluminium foil to avoid turbulence with the wires of the electric current

So I agree with the hypothesis put forward by Peter (PMPeter) if my memories are good, I have a problem with the flat Marklin cord or with the S88 5217 decoders from viesmann or both together.

I've been surfing the LDT site a little bit.

A lot of choices and for a little guy like me, it's the puzzle. What to choose?

What are the differences between

- RM-88-N

- RM-88-N-O

- RM-GB-8-N

The second one (RM-88-N-O) tempts me very much but I don't know LDT products

To conclude, the extended connection cable for the s88-feedback bus seems better than the marklin flat cable.

I need your advice, which as usual will be appreciated.

I have the CS2 and the software Itrain

Thank you

Ok thank you ...... I see that you use both... but I still don't know the difference... I'm sorry but I don't know more... it doesn't matter... I'll send an email to LDT for more info.

But for the price difference I'm probably going to opt for the RM-88-N-O

Adding to the above explanations:

The RM-88-N and RM-88-N-O are connected to one of the outer rails, and react on present wheels grounding the connection.

The RM-GB-8-N is connected to the inner/center rail, and reacts on a present slider/pickup-shoe consuming power.

The RM-GB-8-N was a perfect solution on my M track layout. I would use it also on my C and K track layout, if the cost per input was equal to the RM-88-N-O. (No need for the ”diode trick”.) Both are great products, and I have never experienced any interference.

If using a CS2, you could use a RJ45 internet cable also here, by adding the following products from Tams:

1 x S88-15 (Short 15 cm cable)
1 x S88-A-SL (Adapter)

This makes it possible to have a longer distance to the first S88 module, without interference.

Hi Antonio

I think that only the first must be connected to the ground

I thank everyone for the help you gave me. It was appreciated.

I will be ordering in a few weeks the LDT products that I want right away after finally receiving the news from my native country... long awaited for too long.
