@Jan: in the document linked by Paul
(http://www.maximintegrated.com/en/app-notes/index.mvp/id/148) they start by
saying "The scope of this document is limited to 1-Wire networks that use
Category 5, twisted-pair copper wire and have 5V bus power supplied by the
master"
So i guessed that this was

@Paul: Yes i had read that website some time ago. It made me change (then)
from (mixed) star topology to my current (linear) bus. to accomodate this i
followed the suggestions of the list members and used the utp-wires 4and5
for the dépard and wires 3and6 for the return.

Don't use a pair for 1W and GND, as the

I assume you've looked at some of the resources for 1-wire bus topology,
like http://www.maximintegrated.com/en/app-notes/index.mvp/id/148

I have a plugin board running on top of my pi containing a DS2482-800 and an
2482-100 master. Both are connected through I2C.
The DS18b20's that are connected are connected in bus layout and are powered
