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.

Great price!

Received the Cat comm 3 quickly and the item was new as described. Have tested it with Cat ET, Cummins Insite and Detroit DDL to date.
Would like to add one thing to the review as I did not see it in the others I read before purchasing. If looking to connect to on-highway, adapters 507-1011 is required for the 9 pin (J1939) connection and 7X-1686 for 6 pin (J1708). They are also available from seller but I was unaware and had to order them after receiving. No fault of the seller. Highly recommend.
