Thanks for answer.

Hi guys, hi zeronix
You need more components (resistors) because you need a lower resistance (value) than 4.7K on this bus with 7 probes, for a good operation of your star bus with more than one probe.

Yeah with 1.6 worked like a charm, and was trial and error, before now this kind of particularities.
it's a star bus or normal?

Now U2 @Koepel and @PatMax confused me hehe
