Race Manager Software


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.


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.



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 more accurately determine when a transponder crosses the center line of the start/finish.

Four transponder types are available:

Rechargeable (Yellow) - Charge lasts 7 days. Green light at top flashes the number of days remaining. Fast recharge (max 3 hours, typically 1 hour). ($195 retail)*

Activated-CAR (Green) - A cost effective unit meant for cars of all types. No charging necessary. Replaceable internal battery (battery life 3 years, depending on usage. Non-use shelf life up to 9 years). ($150 retail)*

Activated-KART (Blue) - A cost-effective unit intended for motorcycles, karts and quarter midgets. No charging necessary. Replaceable internal battery (battery life 3 years, depending on usage. Non-use shelf life up to 9 years). ($99 retail)*

Hardwire (Orange) - Eliminates charging hassle. Hardwired directly to vehicle. Hooks to 12VDC battery. ($189 retail)*

* Prices for transponder only. Does not included charger or holders.

Individual Charger


Individual Charger

Transponders are quickly charged with the convenient charging cradle. Max charge time is ~ 3 hours. Typical charge time is ~ 1 hour. LED lights on the transponder indicate full charge while in the charging cradle. When removed from the cradle the transponder green LED indicates approximate number of days of life left (up to 7 days). A red LED indicates when the transponder charge has less than 1 day remaining. ($35 retail)


Bulk Charger (Holds 45 Transponders)


Bulk Charger

Capable of charging 45 transponders, the bulk charger is also a convenient carrying case made from a tough Mil-Spec, IP-67 case. ($750 retail)
