MCON Deployment overview The MCON is connected to the STAR via its Ethernet interface.Figure18 illustrates a typical deployment scenario. The figure illustrates that a single MCON can interface with and manages one or more STAR Receivers.

  • Page 22: System Configuration

    6. System Configuration The MCON has the flexibility to configure and manage the STAR unit through 2 very specific interfaces. The utilities for these interfaces are primarily the Web Graphical User Interface and secondly an engineering Client called Mojo. Additionally, the MCON publishes tag data out through a variety of standardized interfaces for 3rd party integration. These interfaces include Microsoft Biztalk Provider, Web Service Definition Language (WSDL), IBM Websphere, and ALE.

  • Page 28: Emux Calibration

    6.3. eMux Calibration eMux’s must be calibrated to ensure that they amplify the STAR’s signal correctly. Improperly calibrated systems will either exhibit mis-calibrating eNodes which can be seen from the eNode calibration (middle) LED blinking slowly or not illuminating at all when directed to excite tags. In newer systems, an eMux Button on the Web GUI allows for remote calibration by simply pressing the Calibration Button once all hardware has been connected and powered on.

  • Page 29: Appendix A: Location Configuration Guidelines

    Mojix ® STAR 1000 System User Manual Appendix A: Location Configuration Guidelines This section describes the setup and installation notes to estimate location. For most algorithm variations, the location and orientation of the receiver and eNodes is essential for determining tag location. What follows is the description of the coordinate system and the system components in it as well as how to enter this information so that it is accessible by the software applications.
