The Jaltest JDC525A connects the 14-pin round diagnostic connector of tractors from Claas and Renault to the 16-pin OBD2-port of your Jaltest diagnostic cable. On the machine side, there is a black plastic round connector with a knurled ring and male pins; in the fourteen-pin housing, not every position carries a pin, so you can identify the correct connector by the pin pattern. The cable measures 28 to 30 cm and is specified for Jaltest Link V8.1 and V9. The same tractor family is also available with a 4+4-pin diagnostic connector; this is the 14-pin version.
With this connection, the Jaltest software opens the diagnostic line to the tractor's control units. On the heaviest models, the ATLES 9X5-9X6, behind it are the engine controllers EMR and EMR2 - EDC, the central vehicle control unit RCC/RCC2, the transmission controller TC, the valve control ELECTROPILOT and the lifting devices TCE; on the ARES 7X5 it remains with the QUADRISHIFT/TWINSHIFT gearbox and the DBD2 instrument cluster. In agriculture, the standardised OBD connector was never made mandatory, which is why this round connector has remained in use alongside the 4+4-pin version. The cable falls under Jaltest AGV (agricultural vehicles).

Compatible vehicles and applications
The connector type determines compatibility, not the model.This cable fits any tractor from Claas or Renault equipped with the 14-pin round diagnostic connector in the cab.
