RaceTime Hardware Basics

Hardware Setup

To operate the RaceTime automated race timing and scoring system, the user attaches a transmitter to each vehicle, connects the trackside antenna, receiver, and computer, and runs the T&S software.

Vehicle Transmitters: Small transmitters, each with a unique code, are attached to each vehicle in the race. Quick and easy attachment is accomplished using industrial velcro and optional tie-wraps or pouches. The transmitters run on 9 volt batteries, or as an option, on external 12 volts. Up to 400 seperate transmitter numbers are available for standard RaceTime, and up to1,000,000 transmitter numbers are available for RaceTime2 systems.

Trackside Antenna: A small antenna mounted on a tripod is placed at trackside, usually at the start/finish line. Optionally, the antenna can be bolted or tie-wrapped to a fence or other supporting structure. The trackside antenna picks up the vehicle transmitter signals and relays them to the receiver.

Receiver: The receiver takes the signal from the trackside antenna, by way of a standard 25 foot cable, or an optional 300 foot cable and amplifier. The RaceTime receiver's high-speed digital signal processors determine the transmitter number and time of crossing, and sends this data to the T&S computer for display.

	*System Accuracy:* As with all T&S systems, accuracy depends upon many factors, such as vehicle speed, antenna position, etc., but is generally within 3/100 second. Accuracy is not significantly impacted with as many a 10 simultanious crossings. An optional timing light is available for timing accuracies to 1/1000 of a second.

	*T&S Computer* A user supplied IBM PC or equivalent computer, 386 or better, runs the T&S software. Click on software in the menu above to find out more about our outstanding T&S software packages.
