Connecting Cat ET and the Communication Adapter Gp

Illustration 1	g01121866
(1) Personal Computer (PC) (2) 196-0055 Adapter Cable As (3) 275-5121 Communication Adapter Gp (4) 332-7381 Adapter Cable As

Note: Items (2), (3), and (4) are part of the 317-7484 Communication Adapter Gp.

Use the following procedure in order to connect Cat ET and the Communication Adapter II.

1. Remove the electrical power from the ECM.

2. Connect cable (2) between the "COMPUTER" end of communication adapter (3) and the RS232 serial port of PC (1).

   Note: The 327-0375 Adapter Cable As is required to connect to the USB port on computers that are not equipped with an RS232 serial port.

3. Connect cable (4) between the "DATA LINK" end of communication adapter (3) and the service tool connector.

4. Restore the electrical power to the ECM. If Cat ET and the communication adapter do not communicate with the ECM, refer to the diagnostic procedure Troubleshooting, "Electronic Service Tool Does Not Communicate".
