Be careful of clones on eBay! Many sellers are advertising the CAT Comm III as a far less price, but what you are really buying is a CAT Comm II disguised as a CAT Comm III. The old adapter, part # 317-7487, has been replaced with this new model. The adapter itself is the same, the cable ends have changed.
If your are only connecting to on-highway trucks, you don't need this adapter. You can easily purchasing a DG Tech DPA5 or Nexiq USB Link 2 from us for less money and get better coverage. If you are wanting to connect with earth moving CAT equipment, this is the Cat-specific adapter offered here that will do it!
This listing is for a brand new, never used CAT Communication Adapter III. It is the latest generation of the CAT Communication Adapter group, and replaces the CAT Comm Adapter II & the old 317-7487 tool number.
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.
