When a transponder crosses the detection loop, the IDEC captures signals from the transponders and processes the raw data to determine the exact crossing time of each vehicle. It then sends this information to the computer over a serial or Ethernet link for final analysis and storage with Race Manager Software. Data can then be sent from the computer to other devices such as scoreboards, printers, wireless hand-held lap time viewers, and other third party devices. The IDEC can be used standalone or in a network of multiple timing points.

Each transponder has a unique serial number that identifies exactly which competitor is crossing the start/finish line, or any other timing point on a course. Unlike standard RFIDs, Westhold's transponders have an ultra high data rate (1mbit/sec) at HF (3-30MHz) frequencies. Because the high data rate generates many data points, the system is able to determine precisely when a transponder crosses the center line of the start/finish. Recent tests have shown Westhold to be the most accurate system currently on the market.

Westhold's Race Manager Software is free. It can be accessed from the 'Download' section of our website. This powerful software organizes the data coming from the IDEC. It is necessary to store, publish, and print event results.
