Switch to another profile switch to another vehicle s inputs settings calibrations see section on Profiles Point to Point Racing Mode Point to Point Racing mode is for races that start at a starting point and end at a finishing point rally races for example Up to 5 split points may be defined Basic Operation Unlike Circuit Mode in Point to Point mode the GPX cannot determine the start and finish for the race You must create a new track then define the start and finish point And optionally define split points To create the new track go into the menu system go to Track Options then press Select Using the arrows go to Create a new track and press Select Enter the name of the new track using arrows and Select Press Menu when the name is complete Next you need to set the start point the end point and optional splits Again under Track Options select Start finish splits You can now either physically go to that point and capture the coordinates via the received GPS signal or else you can enter the latitude and longitude by entering those numerical coordinates Please note that you do not have to set the start point before you set the finish point you may define the start finish split points in any convenient order Notice that on the menus a check mark is displayed next to each point which you have defined Track options Set start finish splits Coordinates via GPS capture OFF HOME Se

You should notrecord data at a higher sample rate than you need higher sampling rates use up the memory more quickly in the GPX and result in less time that can be stored before data needs to be deleted Press Select on an Enabled entry allows you to change an input from enabled to disabled and vice versa When you press Select on a Cal entry you may then calibrate or uncalibrate that input Each type of data has a different calibration procedure Temperature and switch type inputs may have an alarm set See the section below entitled Alarms The lower portion of the screen shows the current value for the currently highlighted input and information about its calibration Also for analog channels the approximate real time voltage of that input is shown This voltage reading can be useful when trying to determine if you have hooked up the input properly to the vehicle Typical Inputs XT Racing Sensors XT Racing offers several sensors which are directly supported by the GPX Pro without requiring calibration SEO1 pressure sensor 0 150 psi SE02 pressure sensor 0 2000 psi SEO3 thermistor 10 to 150 degrees C RPM The GPX can record RPM data RPM pickup requires that a signal be available on your vehicle 2013 XT Racing which is a pulsed binary logic signal which is typically generated by the vehicle s engine control unit module ECU or ECM Most fuel injected engines will have such a signal available The
3. 1 7 when you go less than stopping speed or if you travel more than 15 miles Introduction to GPS The Global Positioning System consists of a constellation of satellites orbiting the earth There are currently 24 such satellites in orbit It is commonly thought that the satellites are stationary in the sky geostationary like DirecTV or DishNetwork satellites but this is not the case The satellites are constantly in motion if they were not there could be places on earth imagine a canyon in New York City where reception could be essentially permanently blocked Since they are moving any outage would only last for a little while If you are in a big open field up to 12 satellites should be in view at any time Depending on cloud cover atmospheric conditions etc less than 12 satellites may be in view On the main screen of the GPX the number of satellites in view and the relative quality of signal is displayed You may find that positioning the GPX in a different spot on your vehicle may have an effect on signal quality Generally the more open the GPX is to the sky the better the reception Also as a result of the constant motion of the GPS satellites you may find that at the same track on different days or even within the same day you may find significant differences in the quality of signal For accurate capture the GPX requires a minimum quality of GPS sig

13. a start finish line associated with it In actuality it is a start finish point The start finish line is that point on the track at which a line across the track goes through that point The simplest way to get a start finish line at a new track is to do nothing Race around the track and the GPX will find a loop point and use it for the start finish line There are two modes for having the GPX determine the start finish line menu item Track detection method First loop the default is just that the GPX determines the first time a loop is closed and makes that point the start finish line Longest straight requires an additional 1 2 loops around the track and in this case the GPX sets the start finish line about one third of the way down the longest straightaway The straightaway that the GPX calculates allows for some slight variation from a straight line Another way to set a start finish at a new track is to walk over to near where you want the start finish line to be and set the start finish line via the GPX s menu system Track options Set start finish line of a new track This point will now form the basis for the start finish line when you start racing the track Please note that you should be no more than about 50 feet of where your vehicle will cross the start finish line in order for the GPX to recognize it while you are racing Yet another way to set the start finish of a new track is to directly en
