The Florida Region uses the AMB transponder system for timing and scoring of road races. There is a loop buried into the racetracks at the start finish line that registers your transponder number, time and number of laps.

If you want your times to be accurate (and who doesn't)? You got to make sure Timing & Scoring gets your transponder number well in advance. The best way to assure this is to put your transponder number on your registration form and your registrar will get the number to Timing and Scoring.

When you install the transponder; attach it to a location on your car where there is no obstruction between the transponder and the loop in the track. Closed wheel racers usually place them inside a front wheel well. Open wheel racers usually attach the transponder on the side of the tub or bottom.

However, if you rent a transponder at the track, you will need to take your transponder number up to Timing & Scoring to assure that they you are entered into the computer. Without your transponder number Timing & Scoring will not know who you are on the track. And of course you want your new track records recorded - right?

1. If you own your own transponder, write the number down in your log book and be sure to enter it on your T&S registration form when you mail the entry to the registrar.

2. If you borrow or rent transponders, make sure the data gets recorded accurately. Check your wiring and batteries like you check your oil and tire pressures.

There are two types available. Direct wired, 12v or a rechargeable unit. The rechargeable unit has a life of about 4 years and the battery is replaceable (it will NOT last an entire race weekend).
Both units carry a three-year warranty from AMB.

Please contact AMB Transponders to purchase units.

The Region will be offering rental units at a cost of $50.00 per weekend.

TranX260 Direct Powered Transponder The direct powered TranX260 transponder is becoming increasingly popular. In most cases the transponder, once mounted, stays on the vehicle for the duration of the season. The transponder comes with a fixed wire for connection to the 12V battery. Power consumption is extremely low and does not effect the operation of the vehicle in any way.

TranX260 Rechargeable Transponder The rechargeable TranX260 transponder comes with an individual charger which operates through a standard wall socket or through the cigarette lighter in a car. The number of flashes of the green indicator light on the transponder, shows the number of days left before the battery needs to be recharged. Five hours before the battery becomes fully discharged, this indicator light changes from green to red. When this change occurs, also the race organization gets an alarm on its computer screen.

AMB Transponder FAQ

What is my transponder number ?

Your transponder number is the 7-digit number that is printed on the front of the transponder. This number is the one you need to provide on your entry form. If you rent a transponder at the track for the weekend you will need to take this 7 digit number to T & S.

How do I mount my transponder ?

The transponder can be easily mounted on the vehicle, by using the specially designed transponder holder. This holder is permanently attached to the vehicle, with scotch mount tape, ty wraps or pop rivets. The transponder can be placed or removed by simply removing the pin.

The transponder should be mounted so that you can read the logo and transponder number. The bottom of the transponder should be pointed towards the track surface and be located no higher than 2 feet off the ground with no metal or carbon fiber between the transponder and the ground.

What are the advantages to a rechargeable transponder ?

The advantages of rechargeable transponders are that they can be mounted easily in almost any location and, with additional mounting brackets, can be used on more than one vehicle. But it takes up to 48 hours to recharge.

What are the advantages to a Direct Powered transponder ?

The Region recommends Direct Powered because you don't need to recharge the transponder. The advantage of a Direct Powered transponder is that once it is wired up correctly it is ready to go each time the car is started up. There is no need to charge the transponder.
