Or use three wires for GND. (You do have a spare pair of wires in your bus
cable, don't you?)
Frankly, if I had thought of this, the first thing I'd try to fix t

Before voltage drop on the 1W line gets a problem, you have a problem on
the GND line.
That is because when you have 1V dro
Volt drop on some of the cable runs. Just thought if I started with a
higher voltage there would be more left at the end:) I need to work
through it all, probably double up on the +5v line as well to reduce the
volt drop but that means some fiddly soldering on the circuit boards
unless I can

The datasheet of DS2482-800 also says +6V is absolute maximum rating to

Hi Paul,
Thanks for the suggestions. Yes the Sheepwalk adapter is based on the
DS2482-800. I can't see anything obvious in the logs, but I have done
some more investigation and now suspect it may well be a voltage
problem, so I am looking at ways to try to stabilise it.
I see on the spec s
I assume we're talking about the DS2482-800 -- the 8 channel i2c-based bus
master.
The fact that a reboot doesn't fix the problem takes in issue out of owfs
(which should be entirely reset by a reboot) and to the hadware (which
might need a power cycle to fully reset).
The datasheet talks about a
I have had a problem probably 3 or 4 times over the last few months
where I loose some channels on my 1-wire, this time channels 1, 4 and 5,
which I think is the same channels as before but can't be sure. If I
reboot it doesn't help, just comes up with the same missing channels,
but power cycl
