Electrical and Physical Layer Stability of RP1226 to J1939 Cables

Electrical and Physical Layer Stability of RP1226 to J1939 Cables

Electrical parameter matching:

Transmission rate: The J1939 standard transmission rate is 250kbps, and the RP1226 interface needs to support this rate.

Bus impedance: J1939 requires a bus impedance of 120 Ω, and the cables and terminal resistors of RP1226 interface must meet this requirement.

Cable characteristics: The RP1226 interface requires cables that comply with this specification to ensure signal integrity.

Mechanical and functional characteristics:

Interface design: The pin allocation and electrical characteristics of RP1226 interface need to be matched with J1939 connector to ensure the reliability of physical connection.

Anti interference capability: The differential voltage transmission method and shielded twisted pair design of J1939 protocol can effectively resist electromagnetic interference. The RP1226 interface needs to continue this feature to ensure communication stability.
