The Link45 has an advanced 1-Wire front end that presents controlled impedance to the bus, performs intelligent bus pre-charge and has improved waveform timing based on extensive research with a variety of iButton and 1-Wire chip devices and network topologies. Slew controlled drivers reduce EMI and ringing, while analog and digital filtering reduce noise sensitivity. A crystal controlled time base eliminates the need for periodic recalibration steps in the driving software and assures consistent 1-Wire waveform timing.
Link45 has additional features not found in the DS9097U-09. When used with any terminal program, the Link45 can serve as a network sniffer and diagnostic tool.
There are two connectors on the Link45; a DB9 connector attaches to the serial port of the host computer and a female RJ45 connector provides output to the 1-Wire bus. The RJ45 connector is fully compatible with RJ11 and RJ12 connectors, as only the two center conductors are used.
