SUBJECT: AVSpare Monitoring System Module May Experience Cat Data Link Communications Problems

PROBLEM:

When AVSpare Electronic Technician (AVS ET) is connected to a machine, it sends a request to all Electronic Control Modules (ECM) asking for their serial numbers and device information. All ECM?s respond to this request, resulting in a large amount of information on the Cat Data Link. This influx of information may cause the 154-7443 Cat Monitoring System to miss the message, causing AVS ET to assume that the Cat Monitoring System is blank.

SOLUTION:

If AVS ET indicates "blank box" (Illustration 1), perform a second AVS ET software connection. A second AVS ET software connection can be performed by clicking on the "Connect" icon (Illustration 3) that is located on the ET screen. When performing a second AVS ET software connection, it is not necessary to disconnect and reconnect the communication adapter.

 

Illustration 1. ECM Selector dialog.

 

 

 

 

 

Illustration 2. After the user chooses the Cancel Button, the user will see Cat ET in a disconnected state.

 

Illustration 3. The Connect icon.

 

Illustration 4. All three ECM?s shown in the ECM Selector dialog box.
