Teletrac, Inc. - Prism TM2 Information and Installation Guide The Prism TM2 is designed to behave the same way as the VLUplus unit and have the same features available. However, the Prism TM2 is not as programmable as the VLUplus. Instead of having a script, the Prism TM2 has a hard coded set of instructions that can have some small configuration changes. Below is a list of how the unit will act by default; changes to the configuration will be a future implementation.
Teletrac, Inc. - Prism TM2 Information and Installation Guide --------------Unit Four-------------FEATURE COMPARISON Following is a chart to allow you to quickly see each of the features followed by a description of the feature. The chart and feature descriptions are broken down into RF VLU, VLUplus and Prism TM2 features. We will also go over how these features will be implemented to the field.

Teletrac, Inc. - Prism TM2 Information and Installation Guide In Motion detection The Prism TM2 will be capable of detecting when the vehicle is stationary or moving with +/- 1 mph accuracy. Upon detecting either of the events, the Prism TM2 can send messages or begin timers. The ultimate goal of this feature is to eliminate locations unless the vehicle is moving or the ignition is on, which will save location units. (Min.
Zone Compliance or Landmark Detection The feature of Zone Compliance is the capability to store a set of coordinates inside the Prism TM2 that make up an area called a zone. The Prism TM2 can then perform certain actions upon detecting where the vehicle is in relation to the zone. This function acts similar to Exception Conditions in the Fleet Director software depending on how it is programmed. Upon entering or leaving a zone, the Prism TM2 can send a message or change its operating condition.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Speed Threshold A natural spin-off from time and distance is speed. The Prism TM2 can detect its own speed more accurately then Fleet Director (+/- 1 mph accuracy). Because of this, the Prism TM2 can detect speed violations thus alerting dispatch of possible violations or exception condition. Thresholds can be set in the Prism TM2 to trigger warning messages when the vehicle goes above a specific speed.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Message Store and Forward (Message History) The unit has ability to store locations, event history and messages. Any of these pieces of data can be stored while the Prism TM2 migrates outside the GPRS coverage area. The unit will first attempt to send the message or event, if it fails, the message will be sent to a memory buffer for later delivery. When a report is run, the coverage area will appear greater.

Teletrac, Inc. - Prism TM2 Information and Installation Guide GPS performance will be less than optimum when using a hidden antenna. When using this type of antenna, be aware of surrounding obstructions that could further reduce GPS operation. GPRS Antenna The cellular antenna used by the PRISM TM2 for GPRS service is a standard black 3dB gain whip. It mounts with a standard NMO "Motorola" mount and requires ground plane to work properly.
Teletrac, Inc. - Prism TM2 Information and Installation Guide PRISM TM2 INSTALLATION PROCEDURES Once you have all your tools in order and have planned the location of all the devices, you are ready to install the unit. Following are the steps for two types of installations, replacement of an existing VLUplus OR Prism and installation of a new PRISM TM2. Replacing a VLUplus with a PRISM TM2 You can use all the same wiring and only need to switch out the unit itself.
Teletrac, Inc. - Prism TM2 Information and Installation Guide 5. Connect the PRISM TM2 wiring harness as recommended below. For safety, remove fuse until installation is complete. Never tap into existing power or ignition wires used from other aftermarket devices. Ground – Locate chassis ground within one (1) foot of the PRISM TM2 placement.

Teletrac, Inc. - Prism TM2 Information and Installation Guide Appendix A APPENDIX A – AN INTRODUCTION TO GLOBAL POSITIONING SATELLITE SYSTEMS Global Positioning Systems - A Primer Navigation and positioning are crucial to so many activities and over the years all kinds of technologies have tried to simplify the task including Teletrac's RF system. The U.S. DeparTM2ent of Defense (DoD) decided the U.S. military needed a super-precise form of worldwide positioning.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Step 1: Triangulating from Satellites Improbable as it may seem, the whole idea behind GPS is to use satellites in space as reference points for locations here on earth. That's right, by very, very accurately measuring our distance from three satellites we can "triangulate" our position anywhere on earth. Forget for a moment how our receiver measures this distance. We'll get to that later.
Teletrac, Inc. - Prism TM2 Information and Installation Guide So by ranging from three satellites we can narrow our position to just two points in space. To decide which one is our true location we could make a fourth measurement. But usually one of the two points is a ridiculous answer (either too far from Earth or an impossible velocity) and can be rejected without a measurement. A fourth measurement does come in very handy for another reason however, but we'll tell you about that later.
Teletrac, Inc. - Prism TM2 Information and Installation Guide But assuming we have precise clocks, how do we measure travel time? To explain it let's use a goofy analogy: Suppose there was a way to get both the satellite and the receiver to start playing "The StarSpangled Banner" at precisely 12 Noon. If sound could reach us from space (which, of course, is ridiculous) then standing at the receiver we'd hear two versions of "The Star-Spangled Banner," one from our receiver and one from the satellite.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Step 3: Getting Perfect Timing If measuring the travel time of a radio signal is the key to GPS, then our stop watches had better be darn good, because if their timing is off by just a thousandth of a second, at the speed of light, that translates into almost 200 miles of error! On the satellite side, timing is almost perfect because they have incredibly precise atomic clocks on board.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Step 4: Knowing Where a Satellite is in Space In this tutorial we've been assuming that we know where the GPS satellites are so we can use them as reference points. But how do we know exactly where they are? After all they're floating around 11,000 miles up in space. A HIGH SATELLITE GATHERS NO MOSS That 11,000 mile altitude is actually a benefit in this case, because something that high is well clear of the aTM2osphere.
Teletrac, Inc. - Prism TM2 Information and Installation Guide GETTING THE MESSAGE OUT Once the DoD has measured a satellite's exact position, they relay that information back up to the satellite itself. The satellite then includes this new corrected position information in the timing signals it's broadcasting. So a GPS signal is more than just pseudo-random code for timing purposes. It also contains a navigation message with ephemeris information as well.
Teletrac, Inc. - Prism TM2 Information and Installation Guide There are a couple of ways to minimize this kind of error. For one thing we can predict what a typical delay might be on a typical day. This is called modeling and it helps but, of course, aTM2ospheric conditions are rarely exactly typical. Another way to get a handle on these aTM2osphere-induced errors is to compare the relative speeds of two different signals.
Teletrac, Inc. - Prism TM2 Information and Installation Guide If it picks satellites that are widely separated the circles intersect at almost right angles and that minimizes the error region. Good receivers determine which satellites will give the lowest GDOP. INTENTIONAL ERRORS! As hard as it may be to believe, the same government that spent $12 billion to develop the most accurate navigation system in the world is intentionally degrading its accuracy.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Appendix B APPENDIX B – TELETRAC PRISM TM2 ANTENNAS Teletrac has approved 5 antennas compatible with the Prism TM2. Two of these designs are GPS only and need to be installed along with the GPRS only antenna. The other two have both GPS and GPRS antennas. GPS Roof Mount Antenna - Part # 335-0054 This antenna mounts on the outside of the vehicle trough a 5/8-inch perforation of the roof.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Roof Mount Combo Antenna - Part # 335-0060 Self contained antenna that encloses all its components inside a single unit. GPRS and GPS both share the same ground plane in order to minimize noise. The body of the antenna is a 4-inch disc that is 100 % waterproof. Its low profile and ease of installation and high gain makes it a very flexible option. Color is white.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Appendix C APPENDIX C – INSTALLATION EQUIPMENT Metro Equipment Each metro should have the following available on site for the installers. • Eltron Printer – for printing labels to affix to units (TLP 2242 Series or equivalent) Installer Equipment Each installer should have the following equipment in their vanstock.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Appendix D APPENDIX D – HOW MESSAGES ARE USED IN SCRIPTS Message Code Usage General NOTE: The term VLU means all Teletrac location units. The purpose of this paper is to give guidelines on how to standardize message code usage for Fleet Director, MDTs and VLUs. The standardization of message codes is intended to help make it easier to develop and support customer applications.
Teletrac, Inc. - Prism TM2 Information and Installation Guide few codes with similar function or features rather than being expected to handle all codes with different with a variety of possible functions or features. Code standardization should take into consideration both inbound and outbound message usage. It should also consider the limitations within the System, the VLU, the MDT, and the workstation software that force some messages to be reserved or identified for special usage.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Table 1 - Standardized Inbound Message Code Usage IB Codes 0 Definition S&F Location 11-50 MDT inbound canned message 51-58 VLU input messages (i.e. Ign, Alert, etc.) 59-70 VLUplus & PRISM TM2 Zone Entry and Exits messages 71-79 VLUplus PEG script status messages 80-89 90-99 Comments VLUplus & PRISM TM2 uses this message code for S&F locations. The definition of these messages depends on customer requirements.
Teletrac, Inc. - Prism TM2 Information and Installation Guide The following table shows how the outbound message codes could be allocated.
Teletrac, Inc. - Prism TM2 Information and Installation Guide Final Comments The key to good standardization is to keep similar message grouped together and to make the code usage intuitive. Unfortunately sometimes intuitive and grouping don’t mix. The best standardization method would never use the same message code twice however we don’t have that luxury due to limited code availability (especially on the inbound messages).
