I use Intellibox,  Win Dig PRO X.3 (demo version)  HSI 88 (serial port),  RM-GB-8, ( total 17 modules 6+6+5) wires are short  and orderly.

I have a big problem: sometime some feedback section don't report
signal to be occupied during run the train; and somtime some section
feedback don't switch-off signal occuped track after passage of the train....tragedy..
What do you think about this problem?
If I join all modules RM-GB-8 to Intellibox I have not this problem!
Best Regards

Hallo Dario,

there is a hint in this posting that might help you but it's in German. Short translation: HSI might have problems with an odd number of s88. You have 17 s88's. Try to remove one or to add one. Does this help?

Thanks for your answer I have added one and removed but I have that problem again!!

Now HSI 88 is OK! Littfinski has solved my problem

Hello Dario,

which was??

LTD has replaces a small coil with a big coil on power line supply of HSI 88, this has solved problem of interference.
My friend has solved the second problem of missing data, suggesting me to use com 1 and com 4. Before I used com 1 and 3.
