TranX2 Decoder
As the heart of the TranX system, the TranX2 Decoder receives the transponder information (known as passings) from the track, which in turn sends the data to a timing computer. Compact and portable, the TranX2 Decoder is easily moved from track to track throughout your race season. Like all AMB equipment, the TranX2 Decoder undergoes extensive testing before leaving our office to ensure 100% reliability.


Detection loop
The detection loop picks up transponders as they pass over it. Since thousands of tracks across the world already have an AMB detection loop installed at the start/finish line, race day setup is as simple as attaching a few coaxial cables to the AMB decoder and turning on the computer.  The dectection loop comes in two parts: the loop and the co-ax.  The loop is permanently installed in the track. The two parts link together via electrical connectors.

Laptops with Orbits 4 SP2 Software
Orbits 4 SP2 is developed for various motorized sports like Motocross, Karting, Car and Motorcycle racing. Developed by AMB’s Software Division, Orbits 4 SP2 offers the possibility to time several timelines on your track, adjustable print columns, intuitive wizards for starting grids, merging of races, and championship standings, as well as offering a connection for a separate administration computer for race registration and printing of results. GP Sports Timing rents laptops pre-loaded with Orbits 4 SP2 timing software.  All data is cleaned of the computers between rentals so only your data will be visible to you.  You can easily make a back-up file of all your data and keep it on a disc so you can re-load it prior to your next rental.
