( 1 ) J2 is a 70-pin connector. Contacts that are not listed are unused.Input/Output Cat Data Link The Cat data link (connector contacts J1-6 and J1-7) provides a communication link with the other electronic control modules on the machine. The Cat data link is bidirectional. The bidirectional functionality allows the input/output of data between electronic control modules. The Cat data link permits the sharing of information such as engine oil pressure, machine codes and diagnostics. CAN Data LinkThe CAN data link (connector contacts J2-11 and J2-21) provides a communication link with CANIP radios. The CAN data link is bidirectional. The bidirectional functionality allows the input/output of data between the VIMS ECM and CANIP radios. The CAN data link permits the sharing of information.RS-232 Data Link The connector contacts J2-32, J2-33, J2-40 and J2-41 of the VIMS electronic control module provide two RS-232 serial ports. The two serial ports allow the VIMS electronic control module to communicate with the off-board systems. The RS-232 data links are bidirectional. The bidirectional function allows the VIMS electronic control module to input information and output information. One port is used to communicate with an off-board service tool. The second port is used in order to broadcast data to off-board systems, as required.InputsSensing Input (System Voltage) The sensing input for system voltage (connector contact J1-1) tells the VIMS electronic control module the voltage of the machine electrical system. Harness wiring connects the "VIMS" circuit breaker to this input. The voltage helps determine the condition of the electrical system. This input is also the +battery supply for the VIMS electronic control module. OutputsService Indicator LampWhen the VIMS detects an event, the VIMS electronic control module activates the output of the service indicator lamp (connector contact J1-58) and the service indicator lamp is turned ON. The service indicator lamp remains ON whenever the event is active. If an event could damage the machine, the service indicator lamp is FLASHED. The service indicator lamp can be turned OFF
