Set parametersConnecting Cat ET with the Communication Adapter
Use the following procedure to connect Cat ET and the communication adapter to the engine.
Remove the electrical power from the ECM.
If you are using the 317-7484 Communication Adapter Gp , connect the USB plug to the PC and connect the other end of the adapter to the engine's service tool connector.If you are using the 275-5120 Communication Adapter Gp , connect communications adapter (5) to a communications port on the PC by using one of the following methods:

Connect cable (4) between the "COMPUTER" end of communications adapter (5) and the parallel port of PC (1) . Be sure to configure Cat ET for the parallel port.
Connect cable (3) between the "COMPUTER" end of communication adapter (5) and the RS232 serial port of PC (1) .
Connect cables (2) and (3) between the "COMPUTER" end of communication adapter (5) and the USB port of PC (1) .
Connect cable (6) to communication adapter (5) .
Connect cable (6) to a service tool connector.
Verify that the "POWER" indicator on the communication adapter is illuminated.
Establish communication between Cat ET and the ECM.
If Cat ET and the communication adapter do not communicate with the ECM, refer to Troubleshooting, "Electronic Service Tool Will Not Communicate with ECM".Connecting the Digital Diagnostic Tool (DDT) to the Junction Box
