Dear all,

I have got problem with my retro-signalisation.

Historique :

My track is made of C rails (mainly) and M rails
I have an MS2
I have installed Rocrail communicating with the MS2 through CC Schnitte
For the S88, I use ZEUS module from TAM to connect with the laptop.
The occupation if the C rails are flagged by the Marklin S88 AC (60881)

Till here everything is working fine.

When I connect the M-Rails detection, then the problems starts.
For the detection of M rails, I use the Marklin S88 DC (60882) connected to the central rail (power detection).

After the connection of the first box it seems to work more or less properly, but when I connect the second box to the first one I start to have the following errors shown in Rocrail interface:
9999 Protocol Error: unexpected 0x13 got 0x04
or 9999 Protocol Error: unexpected 0x13 got 0x01
and sensor not occupied start to flag on & off in milliseconds

Even when no sectors are connected to this second box (but the T connected to the power), I got error message.

I have already tried different ways for the cables, but it does not solve the problem.

So my question are:
- Is it correct to use the S88 DC for power detection?
- Is there something wrong in my design?

Here is the architecture of my network.
