RP1226-DB9/DB9 adapter cable (J1939, trucks)

RP1226-to-DB9/DB9 Adapter Cable [North American Trucks]

Need to log/stream J1939 data from a heavy-duty vehicle via the RP1226 connector?

The RP1226 14-pin connector is increasingly found in modern North American trucks incl. brands like Kenworth, Peterbilt, Freightliner, Mack, Volvo and more. The connector provides access to J1939 data at either a 250K bit-rate (S-CAN) or 500K bit-rate (K-CAN). This makes the RP1226 connector popular for diagnostics, telematics, fleet management and electronic logging devices (ELD).

With this RP1226-DB9/DB9 adapter cable, you can connect both CH1/CH2 of the CANedge or both 2 x channels of the CANsub, enabling you to auto-detect the bit-rate on both CAN channels. This enables plug & play J1939 data logging or streaming across vehicle models.

About the adapter cable

The RP1226 adapter cable is suitable for various truck brands that expose this connector either as a supplement or alternative to the J1939 9-pin Deutsch connector. The RP1226 connector has increasingly been deployed in North American truck brands, incl. Kenworth, Peterbilt, Freightliner, Mack and Volvo, starting with models from 2019-2023+. It is primarily rolled out in North America, driven by the Technology & Maintenance Council (TMC).

The RP1226 connector is often found behind cabin panels or in the center console.

If you need to collect J1939 data from a compatible heavy duty vehicle, you can connect your CANedge or CANsub easily with this adapter cable. Importantly, the RP1226 connector typically provides access via either S-CAN (pins 2, 9) at 250K or K-CAN (pins 4, 11) at 500K bit-rate. Therefore this adapter cable provides a separate DB9 connector for each of these channels. The RP1226-DB9/DB9 'CH1' connector provides access to the S-CAN pins and power/ground, allowing the device to power up and log/stream data from the S-CAN bus (if it is available). If data is only available on the K-CAN pins aka 'CH2', you simply connect both the CH1 and CH2 DB9 connectors, enabling the device to get power/ground from CH1 and K-CAN data from CH2.

Since the CANedge/CANsub can attempt to auto-detect the bit-rate on both CAN1/CAN2, you do not need to configure the device to match a specific truck model - simply connect both DB9 connectors to log/stream data either on CAN1 or CAN2.

Need to use this with a CANsub.4/CANmod.router? See our DB25-4xDB9 adapter cable.

The RP1226-DB9/DB9 connector is ideal if you know that this connector is available in the vehicles you wish to record data from. However, not all trucks support the RP1226 connector. In such cases, the vehicle often instead supports the standardized 9-pin Deutsch J1939 connector, in which case you can use our J1939-DB9 adapter cable. For additional guidance on selecting the right J1939 adapter cable, see our J1939 data logging intro.

Below are example use cases where the RP1226-DB9/DB9 adapter is useful:

RP1226 S-CAN and K-CAN vehicle diagnostics and telematics

Vehicle diagnostics and telematics

Need to log J1939 data from a mixed fleet of trucks?

In many telematics use cases it can be relevant to record data from a variety of mixed heavy-duty vehicles. For several North American truck brands, the RP1226 connector may be the simplest way to connect. By using the RP1226-DB9/DB9 adapter, you can easily connect both CAN channels of your CANedge, letting you record J1939 data at either 500K or 250K. The result is a plug & play method for connecting your CANedge across any RP1226 compatible vehicles.



Real-time J1939 diagnostics via CANsub

Need to stream J1939 data live from heavy-duty trucks for in-field diagnostics?

Connect the RP1226-DB9/DB9 adapter cable to a CANsub.2/CANsub.4 via USB or Ethernet. Field technicians can then open webCAN in their browser - with zero installation - to stream raw J1939 data live from both S-CAN and K-CAN channels of the truck. With the J1939 DBC loaded, webCAN DBC decodes the frames in real-time (incl. J1939 TP support for e.g. DM1) - ideal for rapid in-field troubleshooting and diagnostics across modern North American truck brands.

Real-time J1939 streaming from heavy-duty truck via CANsub and webCAN



The RP1226 connector is not yet fully standardized, in contrast to e.g. the J1939 9-pin Deutsch connector (see the J1939-13 standard). The RP1226-DB9/DB9 adapter we offer e.g. assumes that power will be available on pin 1 (linked to the ignition). This will most likely be the case in most RP1226 connectors, but there can be exceptions. As such, it is always important to test your setup early on.
