Physical layer testing of RP1226 to J1939 cable performance
Testing the performance of RP1226 to J1939 cables requires a combination of physical layer, electrical characteristics, and protocol compatibility, covering key indicators such as connectivity, signal integrity, anti-interference ability, protocol consistency, and environmental adaptability. Today, we will introduce the physical layer testing of RP1226 to J1939 cable performance:
Appearance and structural inspection
Check whether the appearance of the cable is intact, whether there is damage, indentation or insulation layer peeling.
Confirm whether the specifications of the cable (such as wire diameter, shielding layer, and sheath material) meet the standard requirements of RP1226 to J1939.
Measure cable length to ensure compliance with design requirements.
Connectivity testing
Use a multimeter or cable tester to check the conductivity of the cable, ensuring that each wire (including signal lines, power lines, shielding layers, etc.) is connected properly without any open or short circuits.
Test whether the connection between the terminal and the wire is firm, and whether the contact resistance is within the allowable range.
