Hi everybody


I have 4 s-88 (1 Marklin and 3 Viessmann). I have more than 60 contacts to be connected on the s-88 (1/2 7555 and 1/2 24994)

I want to know if I worked well.

- 1) Only one wire brown in the 1st S 88 for "0"

- 2) Each 7555 has 2 wires : one to S-88 and the second (like a wire brown ) for '' 0''

These brown wires are connected with the ''0'' of the CS2

Correct or no ?

Thank you for yours answers

Hi Serge,

You are correct.

But:
- Don't wire all the stuff in one time
- Always wire & test each S88 after each other, I mean first test S88 #1, then S88 #2 with connection to the previous, then add a new S88, and so on...
- Use a common "0" line
- Try to separate wires going to S88s from the power lines. I mean, don't put S88 wires parallel to power wires to avoid "crosstalk" interferences. If your S88 input lines must cross at various points the power lines, try to use a right angle cross.

Cheers

Hi everybody

I follw the advice of Fabrice and I configured a layout of test S88 on my cs2.

This week I shall test every connection one by one







I hope that it's correct

To see you later..
