The Jaltest JDC539A connects compact Bobcat machines to your Jaltest equipment and splits on the machine side into two round connectors. One branch has contact sockets behind a blue sealing ring, the other has pins in a smooth black sleeve. On the interface side is the 16-pin OBD2. The cable measures 38.5 to 41.5 cm.
Halfway along is a black intermediate piece with a switch in two positions, marked O and I. Beyond it, the Jaltest software reaches the machine computer GATEWAY, the drive DRIVE, the hydraulic control AUX, the engine controls DL02, DM02 and E-CDIS Kubota, and the exhaust aftertreatment control DCU. The cable works with the Jaltest Link V8.1 and V9 and falls under Jaltest OHW.
