The Jaltest JDC107.9 is the USB connection cable for the Jaltest Link V9. It is a black cable measuring 177 cm with a USB-B connector on the interface side in a black housing with rectangular collar, and a black USB-A connector on the PC side with the USB symbol embossed in the housing. This USB-A connector is the difference from the sister version JDC107.9B, which terminates in USB-C on the PC side: if your laptop still has a classic rectangular USB port, this cable is the right choice.
Via this connection, the Jaltest Link V9 is wired to the Jaltest software on your PC, allowing you to run a diagnostic session without wireless connectivity. Which control units you can then access depends on the vehicle and the cable you use to connect to it; this connection cable runs between the Link and the PC, not to the vehicle. Because the cable belongs to the interface itself and not to a vehicle system, it is compatible with every active Jaltest module (CV, AGV, OHW, MHE, Marine and GSE).
