Personal TranX260 Direct Powered Transponder By far the most popular with drivers, the Direct Powered Transponder (DP) needs a quick two-wire connection to the car’s battery to operate. Once mounted to the car using zip-ties or rivets, the DP Transponder requires no maintenance or upkeep. Personal TranX260 Rechargeable Transponder Ideal for cars that have a limited electrical system on-board or cars whose electrical system is an older 6 volt type, the Rechargeable transponder offers drivers increased flexibility in operation. For example, the transponder can be easily switched from car to car where a driver races two cars during a weekend. Though the transponder does need recharging after 5 days of operation, its special charging cradle is designed to prolong the battery life when not in use.
