Do you need to log J1939 data from a Caterpillar heavy duty vehicle?


The cable lets you connect your CANedge/CLX000 CAN logger directly to the CAN bus.


Simply locate the 9-pin deutsch connector in your CAT vehicle, typically found in the cabin


CAN Cable J1939 uses a Type 1 DEUTSCH connector to route J1939 CAN lines to a CiA® 102 D-Sub socket which allows access to CAN interfaces. 


The CAT to DB9 adapter cable is suited for use in most Caterpillar heavy duty vehicles - incl. trucks, transit buses, excavators, construction machinery and more. 


This CAT to DB9 deutsch 9-pin adapter fits most Caterpillar heavy duty vehicles and lets you easily connect your CANedge/CLX000 CAN logger to start recording J1939 data.


DEUTSCH connectors are commonly used for on-board diagnostic connections allowing for the communication and diagnosis between components of construction machinery, agricultural machines, tractors, and other heavy-duty vehicles.


J1939-standard CANbus Solutions


The J1939 protocol set is based on CAN 2.0B and offers a high-speed, reliable in-vehicle communication system for heavy-duty applications.




In-vehicle communication systems differ in many ways from a standard network system. 


In addition to strict demands for high-speeds and reliable data transfer, the system must be able to withstand the harsh conditions encountered by vehicles both on-road and off-road. 


With the advent of IoT, there is an increasing demand for faster and more reliable data transfer to enable fleet management and other cloud-based applications.


J1939 is a vehicle standard for communication that is based on the CANbus automotive protocol.


A J1939 standard system will deliver reliable and high-speed communication and is designed for use in harsh environments. 


This paper will explain the basic structure of J1939, how CANbus is defined within the standard, and challenges associated with in-vehicle communication.





CANbus was released in 1986 and is a message-based, automotive protocol that allows microcontrollers to communicate without the need of a host computer. 


These microcontrollers are also referred to as Electronic Control Units ECU or as nodes. 


CANbus connects to all nodes through a single twisted wire CAN-H and CAN-L 


All signals sent from a node reaches all other nodes, where identifiers within each message specifies the receiver 




The Society of Automotive Engineers (SAE) J1939 describes a standard vehicle bus for diagnostics and communications in cars, trucks and other heavy-duty vehicles. 


J1939 was first released in 1994, while CANbus was included in 2000. 


This set of protocols describes the in-vehicle network all the way from the physical system architecture to communications with software that the user interacts with.

J1939 replaces the older J1708 standard. 


With a limited network speed of 9600 bits/second, it became clear that J1708 was not suitable for the amount of data and sophistication needed for heavy-duty operations. 


With data rates up to 250 Kbits/second, J1939 easily fulfills the requirement for high data transfer speed. 


By 2005 most manufacturers of heavy-duty vehicles had, at least partially, adopted the J1939 protocol as their standard for in-vehicle networking.


J1939 expands on the CANbus protocol by establishing a standard for the higher level layers in the communication network. 

The J1939 system allows for up to 30 nodes or electronic control units
