Donald,
I used an opto-isolated relay board from www.futurlec.com (
http://www.futurlec.com/Opto_Relay_4.shtml) and attached four DS2405 chips
to it. Here is a link to the manual for the board:
http://www.picbasic.it/ETTe/ET-OPTO%20RELAY4%20Manual.pdf
And here is some text I sent to someone else describing what I did:
If you have the manual that comes with the relay board you'll find that to
be helpful. Also the data sheet for the DS2405 (from Maxim's web site). I
just soldered a terminal block (3 terminals) and the four DS2405 chips to
the empty area on the relay board. The terminal block is for connecting
GND, +5V, and 1-wire data to the board. If you arrange the chips one
directly above the other in every other row you can just use solder bridges
to connect all of the GND pins together and then all of the 1Wire pins
together. Refer to my crude diagram below. The DS2405 chips are arranged
with the flat side towards the top of the diagram (so the pins are 3-2-1
from left to right).
....[] <-- +5V terminal
..__[] <-- 1-wire data terminal
..|_[] <-- GND terminal

.ooo.. <-- DS2405

.ooo.. <-- DS2405

I removed one of the connectors from the opposite end of the board and,
using the manual as a reference, soldered wires from the +5V and GND
terminals I added, and from pin3 of each DS2405, all to the appropriate
spots where the connector had been. The connector I removed was a single
row connector with 6 pins (I think). It was the one that the included cable
does not fit on. It doesn't matter which connector you use, since they all
carry the same signals. Just refer to the manual for the pinout.
