Below are two use cases examples where the DB9-J1939 adapter is useful:

SAE J1939 DB9 Connector Adapter Truck Heavy Duty

Heavy duty fleet telematics

Need to log J1939 data from a truck fleet?

In heavy duty vehicle fleets, the simplest way to record J1939 data with your CAN logger is to connect it directly to the CAN bus via a DB9-J1939 adapter. This way, you'll automatically start logging all broadcasted raw J1939 data from the vehicle - allowing you to e.g. set up telematics solutions in no time. The CANedge/CLX000 support optional 'silent mode' to ensure that the device does not affect the CAN bus.

Standalone data logging from transit buses

Need to log J1939 data from a vehicle - incl. on-request PGNs?

In some cases, you'll need to be able to both log broadcasted J1939 data - and request data from the CAN bus. Many J1939 parameters are only available on-request. The CANedge/CLX000 can send custom CAN messages when in direct connection to the CAN bus. The DB9-J1939 adapter enables this when 'silent mode' is disabled.

Request J1939 PGN Data from Bus Fleet



The J1939 adapter fits the vast majority of heavy duty vehicles. However, cases exist where you'll need e.g. an OBD2-DB9 adapter or an alternative heavy-duty adapter. We encourage you always visually evaluate the vehicle in question. If in doubt, feel free to take a picture and contact us. If you need a cable not available on our site, please let us know as well.
