CANchecked CBD06 - CAN bus center distribution

CANchecked CBD06 - CAN Bus Hub

CBD06, short for "CAN Bus Distributor" with 6 connections - why do you need this module?

Connecting CAN Bus devices in your vehicle can be quite challenging. It involves efficiently routing and connecting CAN Bus wires, supplying power to the devices, and finding the right way to terminate the CAN Bus. Furthermore, multiple CAN Buses are often needed to cover different requirements, such as the drive CAN Bus, comfort CAN Bus, and a programming CAN Bus (USB2CAN), among others.

To address this, CANchecked has developed a practical add-on module with 6 connections. Each connection carries four wires: CAN High, CAN Low, 12 V, and ground.

Hardware of the CBD06: With dimensions of just 96 x 47 x 33 mm, the housing is incredibly compact and fits virtually anywhere. The connectors are designed based on the popular DTM04-4P. Optionally, compatible receptacles, DTM06-4S, can be purchased to complete the installation. For installation, two holes are provided in the middle, and the two included screws can be used.

Configuration options for the CBD06

Under the bottom cover, there are jumpers on the circuit board:

On the left side, JP3 and JP4 connect both CAN Buses (CAN Bus 1 and CAN Bus 2). By removing both jumpers, both CAN Buses are separated, each with four connections.

JP1 activates the termination for CAN Bus 1.

JP2 activates the termination for CAN Bus 2.

Optionally, the housing can be equipped with a 12 V/Ground power cable. This cable can then be looped through to the other ports to supply power to end devices. However, devices with higher power consumption should not be powered through the unit. In such cases, connect them only via the CAN Bus lines and establish a separate power supply.

If you choose the default configuration, all 6 CAN Bus connections are interconnected, and both CAN Bus termination resistors are activated.
