Indeed.
That design is based on the DS2409, which is being discontinued (or at
least not recommended by Maxim for new designs).
Someone mentioned here a couple of weeks ago that it is hard

Having decided that I need to add a hub to my system I am having great
trouble finding one.
I saw the AAG unit on the owfs site, but it is not listed on their
website and they don't seem to answer emails.
I saw the Linksys router hack but it seems that only works up to version

I'm no expert but from what I read in "Guidelines for Reliable Long Line
1-Wire® Networks" the best solution is to split in the middle.

I know I wrote about this few times but there was some update on DS2324
substitute.
There is a board and ATTiny44 program which works just like DS2423
We will be coming out with a replacement for our Hub. It is in the
design stage. There are a few other things that have to get
completed before it gets much attention but it is a high priority.

Thanks Marc
I have connected my network with RJ11 plugs and sockets at many of the
junction points, so if there is a problem I can remove sections to
isolate the problem. I think I am well within 1000ft, so I guess I will
stick my current configuration.
Thanks for your help

Mick,
The problem with 1-wire is that it is has "single ended" data
communications signaling vs. "differential" in rs485 or ethernet over
cat5. If you have the differential on a single twisted pair, the signal
will be very resistant to external noise. With single ended systems,
noise is always

I have noticed in other threads that many people use hubs in their

currently have a single network with 25 DS1820's and a couple of

Hi everyone,
With the DS2409s now being Not Recommended for New Designs (NRND) by
Maxim, is there any sane way to do one-wire hubs?
To cut a long story short, basically I'm in need of an insanely huge
one-wire network (many hundreds of meters long), and I'm trying to work
out whether I use a
