AMBrc Direct Powered Transponders

CRCCCC purchased an AMBrc receiving unit and decoder that connects to the lap-counting computer in Autumn 2002.

Club members purchase their own 'personal' transponder units that attach permanently to their car. Each unit has a unique identification number, which is added to the race control program to identify your car during races. Because it is powered from the receiver, the transponder is active when you switch on your car.

The cost of one unit is about £60. These are the details of the AMBrc 'personal' transponder:

Specification
Dimensions	22 x 38 x 7 mm
Weight	6 g
Signal transfer	magnetic induction
Power feed	free receiver socket (ch3 or batt)
Connection Plug	Standard servo plug
Power consumption	Uses > 10mA

Using transponders has many advantages:

· Races are timed more accurately and reliably than manually pressing computer keys

· Because someone is not required to manually count laps, races can run automatically in sequence

Other clubs will switch to the AMBrc system, which replaces the older AMB20, so you will be able to use it at other races. If you have not got a transponder, please consider buying one. They are available from the AMB distributor, bbk Software in Newmarket, web site www.bbksoftware.com
