    Caterpillar Communication Adapter CAT ET 3 Diagnostic Tools 466-6258 Version: 538-5051


    The “old” CAT Comm 3 (Part # 466-6258 & 317-7484) has been replaced with this newer CAT Comm 3 (part # 538-5051). With new firmware and new cables, this CAT adapter is better than ever!

    The latest generation of the CAT Communication Adapter group, and this replaces the CAT Comm Adapter II. This is the only recommended communication device for CAT and the only datalink device that will allow you to properly communicate with a CAT engine on dual datalinks. This function is needed for some CAT ET (Electronic Technician) functions. This is also the only cable that will communicate with CAT off-road equipment when used in conjunction with the CAT ET software. This is a genuine CAT, not a clone or knock-off.
