Hi Guys,
I'm just creating my 1-wire bus, and looking for some practical advices
here - how to connect the devices to the bus?
1-wire recommendation says that a schottky diode and a resistor is highly
recommended to use for each "leg" (which has to be as short as possible,
<1m). I'm planning to build a 30m long, 20 sensor bus based on CAT5E. Will
I need to use the diode and resistor, or will it enough for me to just
plainly connect them without any additional electrical components?
And what kind of connector do you use to add the devices? Which is easy to
build, and easy to repair - and robust enough. In my prototype I use a
wall-mount UTP connector, with 2 UTP slots. Bus comes in one slot, and goes
forward on the other using normal UTP pach cables - of course, I connected
the appropriate pins of the two slots on the back of connector PCB. When I
want to add a new sensor to this "node", I just insert these wires to the
knives (where normally the wall UTP cable connects). I can install up to 6
sensors to one node with this.
However, I'm not completely satisfied with this solution. I'd like to avoid
soldering - how you do it, what do you recommend?
Thank you,
Attila
