Connections for the Communication Adapter 3 and Caterpillar^® Electronic Technician (Cat^® ET) The components that are needed to use the Communication Adapter 3 and Cat^® ET 466-6258 to determine diagnostic codes are listed: (1) Current version of Cat^® ET software (2) 538-5051 Communication Adapter Gp (3) 457-6114 Cable As (DATA LINK) (4) 370-4617 Cable As (CA3 PC USB Cable)

When using Cat^® ET to diagnose machines covered in this manual, cable assembly 457-6114 is required. This harness allows connections between a 9-Pin Port Connector or a 14-Pin Service Port Connector with Ethernet and the Communication Adapter 3 module.

The new 14-Pin Service Port Connector is designed to work with machines that use a 9-pin Service Port Connector. The new 14-Pin Service Port Connector includes an Ethernet port connector which allows for flashing software using Ethernet. These machines require the use of the 14-Pin Service Connector Cable for the CA3 Communication adapter.
