Description

Where on the SB2240 (not the SB0000) can I connect additional CAN BUS devices?
I see a small connector on the lower side of the PCB that is connected directly to the CAN L and H pins; however, there is nothing in the documentation that talks about this. Can I safely use this connector for downstream CAN devices? I want to connect an IDM scanner using CAN BUS.

Research direction

Start by checking the SB2240 documentation and the pictured lower-side PCB connector, including its direct CAN L and CAN H connections. Confirm whether it is safe and supported for downstream CAN devices such as an IDM scanner, then document the connector location, limitations, and usage guidance.
