SymPol transceivers are immune to cross-wire faults

Keywords:Cross-wire faults  cable connections 

Cross-wire faults are a significant problem in many applications where installation of end-equipment and cable connections are made by third party installers, rather than by OEM technicians. Texas Instruments has developed a transceiver which is immune to cross-wire faults.

Data signaling between the various parts of a system enables "smart" functions such as power management, diagnostics, and optimal operation. For this reason, networking and interconnection of equipment is a valuable and growing area of innovation for all sorts of industrial equipment. In many networked equipment applications, the end-equipment units are installed at a site and connected together by local installers. For example, heating/ventilation/air-conditioning system or building security systems have several components, which are typically located around various points in a building, and which must be connected with cables which are cut-to-length at time of installation. This installation is prone to mis-wiring, which can cause data corruption or even equipment damage with most existing types of network signaling schemes (e.g. RS-232, RS-422, RS-485). Identification and correction of the mis-wiring can be difficult once the system is installed, as the entire network may be affected by a single cross-wired node.
