I'm still working on this trying to communicate with ds1820 temp
sensor using bs2p over 1000'. Has anyone dealt with the ds2480b 1-
wire serial line driver.

Let me give you an advice,
take a variable resistor 0-5k to ajust the good value.
I have just needed a 1.8k in my 1-wire bus of 100 metres long.(with crc
error sometime !, so for 1000'=?)
for ds2480 look at

Have a good time.
