This layout of the components makes it easy for the assembled unit to fit into the casing.

Heat shrink tubing is used to prevent shorting.

DS9097U-09

Link12 / Link45

The "Link" provides an ASCII interface to Dallas 1-Wire or Fox-Bus networks. Links come in several variations but all are microcontroller-based replacements for the Dallas DS9097U-09 and provide increased reliability and performance particularly on large or complicated 1-Wire networks. The Link uses an advanced bus interface and intelligent algorithms to make 1-Wire® communications more reliable at short and long distances. (The algorithms and interface for this device were originally developed at Dallas Semiconductor.) The LINK works with Dallas TMEX and iButton Viewer software whether connected to 1-Wire or FxB networks.

The Link12 has been replaced by the Link45 with which it is physically and electrically compatible
