User Guide, WherePort IV D1300 REV A

5.1. This Guide

This guide presents the basic principles of WherePort IV communication and the major issues for placing

them on a site. It is intended to support both the planning for and the implementation of an RTLS

application using WherePort IVs.

It describes the WherePort IV, the WhereTag and its responses, the characteristics of the magnetic field,

and how the WherePort IV is used in a variety of applications. For more detailed information about the

WhereTag see the WhereTag Users Guide.

Also included is a description of the simulator program and how it is used to determine effective

WherePort IV site placement and configuration.

5.2. The WherePort IV

The WherePort IV is a round, dome shaped device, (7.62 inches in diameter and 2.62 inches thick). It is

designed for mounting indoors. It is powered by either 48 VDC POE (Power over Ethernet) or 48 VDC

power adapter. The complete specifications are shown in Table 1. The wiring schematic is shown in

Figure 2.

The WherePort IV is configured using commands sent through the Ethernet POE input or by a separate

RS-232 interface. These commands are described in Appendix B.
