Product Information

Product Description

The DB9-J1939 adapter cable is suited for use in most heavy duty vehicles - incl. trucks, transit buses, excavators, construction machinery and more. The cable lets you connect your CANedge/CLX000 CAN logger directly to the CAN bus. The DB9-CAT variant is used in many Caterpillar vehicles.

Simply locate the 9-pin deutsch connector in your vehicle, typically found in the cabin (sometimes behind a panel).

We offer two variants: A standard J1939 Type 2 adapter cable, used in most heavy duty vehicles - and a CAT adapter cable, used in many Caterpillar vehicles & engines.
