All Caterpillar machines that are equipped with the Vital Information Management System (VIMS) utilize a RS-232 Service Port (5 pin connector) to access and download service information from the VIMS system. The service port was not designed to be used as remote monitoring site for a radio network. Service Program Codes (SPC) that are reserved for use by service technicians are accessible to the operator or other non-maintenance staff while the service port is connected to a radio network. The parameters that are listed below are a few examples of the information that an operator would be allowed to alter:
- Target Payload
- Payload Speed Manager Overload Limit Percent
- Payload Calibration
- Odometer
Caterpillar recommends that you do not connect a full time radio network to the RS-232 Service Port because of the security features of the VIMS will be compromised.
