1. System Components A Mojix STAR system is a single network element at the enterprise edge. Based on Mojix’s innovative distributed architecture, a single system consists of one or more STAR receivers managing up to 512 low-cost Mojix eNode transmitters.
® Mojix STAR 1000 System User Manual 1.3. STAR interrogation spaces Fixed or mobile, STAR interrogation spaces are business process-specific and can be optimized for tag density or coverage. Each individually controlled interrogation space is created by the deployment of single or multiple eNodes and is dynamically sized by the STAR system, which controls each node’s power output. 1.4.
From the figure, the STAR RF output is cabled to the four (4) eNodes in a daisy chain configuration, followed by an eMux. In this example only two out of the four available eMux outputs are use to further connect to two strings of daisy chained eNodes. Lastly, there are the two eNodes at the end of each chain with a 50 Ohm termination.

® Mojix STAR 1000 System User Manual 5. Master Controller Installation 5.1. Master Controller (MCON) Hardware requirements MCON requirements (supplied by Mojix) are: † Linux Operating System † Memory : 4 Gigabytes † Hard disk : 150 Gigabytes † Processor: 3.0 GHz Intel Xeon Dual-Core Please note that this hardware is currently only available through Mojix as a turnkey appliance. 5.2. MCON Deployment overview The MCON is connected to the STAR via its Ethernet interface.
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. 6.1. Network Setup 6.1.1.
® Mojix STAR 1000 System User Manual Figure 20: Network Configuration Changing the IP of the STAR: To change the STAR IP requires a telnet session. The following examples assume the availability of a telnet Client, such as PuTTY (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html). The same PuTTY Client can be used to establish a Telnet connection. Likewise, a telnet session from the MCON command prompt or a Windows XP command prompt may be used as well.
Figure 21: Committing Network Settings To exit from a telnet session, the user must enter ‘ctrl-]’ and then type “quit” (ctrl = control key). 6.2. Graphical User Interface The Web Graphical User Interface (Web GUI) provides the user a simplified HTTP based interface to configure and run the system. Currently, the only supported browsers are Mozilla Firefox and Microsoft Internet Explorer. To launch the Web GUI, enter the MCON IP address in the URL field of the browser.
® Mojix STAR 1000 System User Manual This interface is divided into 2 sections: Master Controller Options and Utilities. The Master Controller Options area allows the user to configure and run the system. The Utilities area allows the user to run diagnostic utilities. 6.2.1. Hardware Button The Hardware Button launches the configuration interface for the STAR.
6.2.2. Reader Button The Reader Button launches an interface that gives the user controls to run the system. Figure 25: Reader Interface – showing tag reads 6.2.3. Network Button The Network Button launches an interface to configure network settings for the STAR and MCON, and was discussed early in Section 6.1.2 and shown in Figure 19. 6.2.4. Status Button The Status Button launches an interface used to view diagnostic messages.
® Mojix STAR 1000 System User Manual 6.2.5. Phpmyadmin Button This Button launches password protected MySQL browser utility and should only be used by advanced users. 6.2.6. dbPlot Button The dbPlot Button launches a Java application that provides various graphical diagnostic functions. Figure 27: dbPlot, graphical diagnostics 6.2.7. Topology Button The Topology Button launches a diagram of the system topology as configured by the user.
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.
® 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.
Property aiaDottedIP, aiaName Comment Network address and reader name Example 192.168.77.100, ‘aia109’ posXFt The X position (ft) of the STAR reader 0.0 posYFt The Y position (ft) of STAR reader 0.0 posZFt The Z position (ft) of STAR reader. The ground is usually chosen to have a z coordinate of 0, so this represents the height of the reader. 5.0 boresightCoazDeg Coazimuth, in degrees, of the direction the reader is pointing.
® Mojix STAR 1000 System User Manual Here are some examples of the coordinate systems that can be chosen (Always use x and y as the horizontal coordinates.) 1) Pick reader as origin, the direction it points as the x-axis STAR Receiver parameters (posXFt, posYFt, posZFt, boresightCoazDeg, boresightElevDeg) are all zero.
Appendix B: Deployment Example B.1 STAR Topology Examples & Deployment This appendix illustrates an example topology and deployment following figure illustrates interrogation spaces and targeted locations for installing eNodes (i.e. labeled one through seven). The figure below shows the eNodes and their associated pointing angles, as well as the position and pointing of the STAR receiver.
® Mojix STAR 1000 System User Manual B.2 STAR System Cabling Example The following figure illustrates an example, showing the cable lengths between each segment of an example deployment. From the drawing, a measurement the insertion loss of each segment is computed, as shown in the figure below. This information is used for placing the eMuxes, to maximize power distribution across all eNodes.
Appendix C: Advanced Troubleshooting C.1 Accessing the Command Line For advanced configuration working beyond the web interface of the MCON, users will need an SSH Client, a VNC Client and an FTP Client capable of using the SFTP protocol. The following list provides 3 suggested utilities and corresponding links. 1. SSH Client – PuTTY: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html 2.
