Schematic of the “Cat Data Link” Circuit
The Cat Data Link is an input and an output of the Machine ECM. The Cat Data Link connects to the Machine ECM at connector contact J2-16 and J2-25. The data link is designed to carry communications between the controller and the monitor. The data link is not a visible component. The data link consists of internal control circuits and a harness wiring. The data link is bidirectional. The controller can receive information and the controller can send information through the data link. The controller sends information about the fuel level, temperature of the engine coolant, and many other signals to the monitor panel.CAN Data Link

Schematic of the "CAN Data Link" Circuit
The CAN data link is used for communication between the following modules: Machine ECM, Switch Panel and Monitor. Two 120 Ohm terminating resistors must be installed in the wiring harness in order for the CAN data link to function properly.Action Alarm
The action alarm SOUNDS in order to alert the operator when a high emergency condition is present. For example, the engine oil pressure decreases below a set value.Travel Alarm
The travel alarm SOUNDS in order to alert the area that the machine is moving.
