Transponders

Track Boxes will only perform according to specification when participants transponders are worn correctly, when using bib transponders this means that the bib is worn on the front of the torso and is not covered.

Higher performance can be expected when transponders are in free air, such as when using MTB number plates or seatpost stickers. Weaker or more restricted transponders, such as HuTags or Disposable Triathlon Transponders, will result in reduced performance and are not recommended to be used. 

Please note that old transponder types or models may not work with the Track Box, the device is optimized to work with the RACE RESULT passive transponder.

Angle of Antenna

To maximize the opportunity to detect transponders, Track Boxes should be setup perpendicular (90 degrees) to the direction of travel. This increases the opportunity to detect transponders which may be worn incorrectly and also helps to ensure transponders are detected regardless of the direction of travel.

If Track Boxes are angled to face participants then the transponder can only be detected when worn visibly on the front, this also increases the distance between antenna and transponders which may reduce read rates. 

Free Standing vs Hanging Boxes

Real-life data shows, that hanging a Track Box Passive higher up, will give you better read rates. Hanging boxes higher up avoids some of the risks of free-standing boxes such as blockages from spectators or uneven ground which may impact the detection field. 

Particularly as split points may often be set up by lesser experienced timers it is important to ensure they are familiar with the setup precautions which may impact the different setup methods.  

Single Box Performance

Although the Track Box may detect passive transponders up to 25m away, long distances will result in reduced read rates. 

When using a single Track Box then the maximum width should be restricted to 4m, this can offer read rates >99% when setup correctly. 

Dual Box Performance

Track Boxes are optimised to be used in pairs with boxes set up on opposing sides of the timing point using Dual Track Box Synchronisation.

Nearby boxes communicate with each other using the built-in 2.4Ghz and automatically synchronise their readers to prevent interference between them.

In this setup then >99% read rate can be achieved at up to 8m wide.
