The WherePort III is equipped with an RS-232c interface that allows easy programming, and firmware upgrades. The RS-232c interface also allows real-time control of the WherePort's functions including power level and tag commands. It also provides the ability to load information into a WhereTag III for transmission to the RTLS infra-structure for process control applications. The WherePort III can also be equipped with an optional status-monitoring transmitter that broadcasts health and status information to the WhereNet RTLS infrastructure.
WherePort III is a proximity communication device that is used to trigger a WhereTag III to transmit an alternate "blink" pattern. When a WhereTag III passes though the WherePort's field, the tag can initiate a pre-programmed and (typically) faster blink rate to allow more location points as a tagged asset passes through a critical threshold, such as a shipping/receiving dock door or from one zone to another. When the WhereTag III is sending WherePort-initiated blinks, the tag includes the identification number of the WherePort. More than 36,000 unique identification numbers are available.
The WherePort III emits a field is nearly spherical and its range is adjustable from approximately 1 m (3 ft) to 7.5 m (25 ft) with proper orientation. For especially large thresholds (such as very large dock doors) or areas where there may be signal blockage, multiple WherePorts can be interconnected to provide a larger coverage area. Addi-tionally, WherePorts can be used to delineate between adjacent doors or lanes when a tag may pass through one of multiple openings.
Designed for indoor and outdoor applications, the WherePort III is sealed against dust and water. A heavy-duty version is available for mobile installations. Each WherePort III includes an adjustable mounting bracket and requires only AC or DC power. Data cables are not required for basic functions, but can be utilized for more complex applications.
