There is no power connection to a 2413 - the I/O is parasitic powered and the outputs are open drain mosfets, inputs look for less than ~3.2 volts for a logic low (but that depends on the 1-wire speed and what the internal charge pump voltage is!!) -- Robin Gilks ------------------------------------------------------------------------------ Slashdot TV.
