Cat Data Link SMCS - 7610-DTN

The CAT Data Link is a communication link that is used for the movement of data between electronic e lectronic controls. The CAT Data Link allows communication c ommunication between the power train electronic con trol module (ECM) and the Caterpillar Monitoring System. The CAT Data Link is bidirectional. The CAT Data Link allows the power train ECM to input information. The CAT Data Link allows the power train ECM to output information. The CAT Data Link is not a visible component. The CAT Data Link consists of the following parts: internal circuits of the power train ECM, the related harn ess wiring and the service tool connector. The CAT Data Link and the power train ECM are connected at pin-out J1-10 and pin-out J120. The power train ECM and the Caterpillar Monitoring System use data that is sent back a nd forth on the CAT Data Link. The following information is some of the information that is shared: l

The power train ECM receives service commands from the Caterpillar Monitoring System in order to change the operating modes mod es of the power train electronic control system. Th e service commands can direct the power train ECM to read service codes that are stored in the memory of the power train ECM. The service commands command s can direct the power train ECM to c lear service codes that are stored in the ECM memory. The power train ECM receives the harness co de input from the Caterpillar Monitoring System. The power train ECM determines the sales model of the machine from the harness code cod e input. The power train ECM sends signals to the C aterpillar Monitoring System. The Caterpillar Monitoring System uses the signals to report on the status of the power train electronic control system. The Caterpillar Monitoring System alerts the operator of the status by illuminating the corresponding alert indicator. The power train ECM sends the information that follows to the Caterpillar Monitoring System:  parking brake status, status of the transmission transmission direction and status of the transmission speed. The Caterpillar Monitoring System displays the transmission direction that is selected and the transmission speed that is selected. The Caterpillar Monitoring System uses this information in
