STOP
   
2. Verify that the Correct Communication Adapter is Being Used
A. A 317-7484 Communication Adapter Gp must be used to communicate. The following communication adapters cannot be used because the communication adapters do not communicate over both data links:
- Wireless communication adapter
- 7X-1701 Communication Adapter As
B. Determine the communication adapter that is being used.     Communication Adapter     Result : An incorrect communication adapter is being used.
Repair : Connect a correct communication adapter. Refer to Troubleshooting, "Electronic Service Tools", if necessary. Attempt to establish communication. Continue with this procedure if the communication adapter does not communicate on both data links.
Result : A correct communication adapter is being used. However, the "Power" indicator is not illuminated.
Proceed to Step 5.
Result : A correct communication adapter is being used. The "Power" indicator is illuminated.
Proceed to Step 4.
   
3. Check the Version of the Firmware for the Communication Adapter.
Note: The version of the firmware for the communication adapter must be "3.0.0" or higher.
A. Electronically disconnect Cat ET. Verify that the "Power" indicator on the communication adapter is illuminated.
B. Click on the "Utilities" menu.
C. Click on the "Comm Adapter II Toolkit" menu.
D. Wait for the tool kit to open. Then, click the "Utilities" menu.
E. Click "Application Firmware Flash".
F. Select the latest ".apf" file from the list.
G. Click "OK". Then, click "Begin Flash".
H. Wait for the "Flashes Completed Successfully" message to appear.
I. Click "Toolkit". Verify that the "Application Firmware Version (Serial IP)" is "3.0.0" or higher
J. Attempt to connect Cat ET.
    Communication Adapter Firmware     Result : "Cat" ET communicates on both data links.
STOP
Result : "Cat" ET does not communicate on both data links.
Proceed to Step 4.
   
           
4. Verify That Cat ET is Configured Correctly.
Note : Cat ET must be configured correctly in order to communicate on both data links. Perform the following procedure:
A. Click on the "Utilities" menu.
B. Click on the "Preferences" menu.
C. Select the "Communications" tab.
D. Verify that "Caterpillar Communication Adapter II (Serial IP)" is selected.
If "Caterpillar Communication Adapter II (Serial IP)" is not an option for selection, the version of Cat ET is incorrect. Version "2007B" or higher must be used.
Update the version of Cat ET. Then, perform this Test Step again.
E. Verify that the port is correct.
F. Verify that the "Enable Dual Data Link Service" option is checked.
G. Click "OK".
Note : Cat ET must reconnect in order for any changes to be used.
H. Electronically disconnect Cat ET if changes are made to any of the settings for communications. Electronically connect Cat ET. Attempt to establish communication. Observe the indicators on the communication adapter.
A "limited support" warning should not be displayed. The "J1939 / DeviceNet" and "CDL" indicators should be flashing. The indicator indicates that Cat ET is communicating on both data links.
    Cat ET     Result : Cat ET communicates on both data links.
STOP
Result : Cat ET does not communicate on both data links. The "POWER" indicator is not illuminated.
Proceed to Step 5.
Result : Cat ET does not communicate on both data links. The "POWER" indicator is illuminated.
Proceed to Step 6.
