About the J1939 adapter
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. See also our DB9-CAT variant, which 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).

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