  • Page 6: Welcome To Team Traqmate

    Traqmate was designed by racers and is great for getting the first or last second out of your lap times. It is also great for the track day enthusiast who wants to record their day, play it back with their video, analyze their performance to get the most out of their car, and do a little bench racing with their friends.
  • Page 7: System Overview

    Traqmate Features Drop and Go – Stick a Traqmate in your car, turn it on, and collect data all day long. No sensors required. Replay Your Day – Upload the data into Traqview. See your car on the track and your performance on the virtual dashboard.
  • Page 8: Traqmate System Components

    Display Unit, in which case it is entirely remotely controlled. When used alone (Traqmate Basic), the Sensor Unit has a single red button on the front panel for ON/OFF and for entering and exiting data recording mode.
  • Page 9: Traqview

    For an added dimension, the optional TraqStudio allows simultaneous synchronized playback of data and video. Traqview is your single point of contact for everything in the Traqmate System. Use it to upload data from Traqmate, analyze the data, configure Tracks, Drivers, Vehicles and optional Sensors, change the Sampling Rate, and even download future software and feature upgrades into your Traqmate.

    Quick Guide – Let’s Collect Some Data You just bought a Traqmate Complete and you want to try it out. This is as simple as it gets. First, install the software. Put the CD in your drive and follow the directions. For most users it is seamless.
  • Page 12: Traqview Software Installation

    Choose a Driver Location and enter: C:\Program Files\Track Systems\USB NOTE: When you launch Traqview and attempt to connect to the Traqmate, if the USB port is not automatically recognized you will be prompted for the COM Port number. Choose AutoConnect and the software will find the right port.
  • Page 13: Traqmate Installation

    Figure 2 - Traqmate Basic Connections Sensor Unit Installation The Traqmate sensor unit may be mounted using a variety of methods depending on the following factors: 1) How permanent is the desired mount, 2) where is the preferred mounting point, 3) will the SU be connected to a Display Unit (DU).
  • Page 14: Traqmate Basic Installation

    Traqmate Basic Installation If the SU is going to be used in a configuration without the DU (Traqmate Basic), it is desirable to have access to the SU for downloading the data once it has been stored. Similarly, if a laptop is going to be used to download the stored data without removing the SU, the unit should be placed in a convenient and accessible location.
  • Page 15: Power Connection

    In all installations, the SU must be supplied with a power source at all times it is in operation. For Traqmate Complete, the DU can receive power via the DIN extension cable from the SU or via the USB cable when connected to a PC for uploading sessions.
  • Page 16: Traqac Power Supply

    With the Display Unit Mounting Bracket, the DU can be snapped quickly and securely into the mating portion of the bracket, which remains permanently affixed to the vehicle. Care should be taken to avoid strain on the DU cable. Copyright © 2005 - 2008 Track Systems Technologies, LLC Page 16...
  • Page 17: Connecting To The Sensor Unit

    DU and SU are incompatible. Reload the firmware of both the SU and DU with the latest downloads available on the traqmate.com website and try again. Copyright © 2005 - 2008 Track Systems Technologies, LLC...
  • Page 18: Traqmate Basic

    Traqmate Basic System Description Traqmate Basic is the easiest form of data acquisition. You can literally just Velcro the unit into a car and get very sophisticated results in a matter of minutes. Data is stored in Flash memory inside the Sensor Unit and can be downloaded through the COM serial port on the front panel of the unit.
  • Page 19: Traqmate Complete

    System Description Traqmate Complete builds on the Traqmate Basic simplicity to add immediate feedback to the driver in the form of lap times and other information on a Display Unit (DU). It also provides more visibility and control of the collected data and useful tools for vehicle performance tuning. The DU provides complete control capability allowing the Sensor Unit to be remotely mounted.

    GPS signal is acquired. If this takes more than a minute, check your antenna connection and ensure that the antenna has a clear view of the sky. Once Traqmate has GPS signal, it will check to see if there is a Start/Finish position stored for the current track. If not, you will see Figure 12 - Recording a Start / Finish Location Proceed around the track until you reach the Start/Finish line.

    Using the Predictive Lap Timer If you are like many Traqmate users, once you have the graph, you will wonder how you did without it. The real-time feedback on your driving is there whenever you need it and can be used in several ways.
  • Page 25: Autocross / Rally Mode

    Lap Timer. For very long courses (> 5 miles), you may want to spread out the updates. If you choose the wrong setting, Traqmate will run out of intermediate storage and your Predictive Lap Timing will not be accurate at the end of the lap. The default MED setting is good for any lap under 5 miles in length.
  • Page 26: Segment Timing Mode

    The concept for this mode is very similar to Lap Timing except that there is a separate Start and Finish. Once you have set the Start and Finish, Traqmate retains those positions for future use at that track and Traqview will use them for analysis.
  • Page 27: Traqview Analysis And Configuration Program

    May 31, 2008 Traqview Analysis and Configuration Program Traqview is the source for configuring, uploading, and analyzing data from your Traqmate. After installation, you can launch the program from the Windows Start Menu or a desktop icon. TraqStudio includes all Traqmate functionality, along with video integration so that you can play back data and video together and save video files with overlayed data graphics.
