Hi, I have had some problems with the 6 channel master hub, very unreliable operation at times, after some debugging, I noticed that the RC-filter that is on the 1-wire line, directly on the DS2480B line driver output, seem to be backwards (compared with the chip datasheet). The RC-filter consists of resistor R5 and capacitor C11, but the capacitor is connected on the wrong side of the resistor R5. After fixing this, the reliability problem almost disappeared. I have a somewhat long network, not very many devices, but about 70m (230ft) of CAT5 cable. Have anyone else noticed this?
