Operation Description:There are problems that may be reported by the Product Link PL102C system but the problems are not caused by the Product Link PL102C module. The following section describes the problems. The section contains steps that are used to determine the possible cause. The module, the antenna, and cables should be visually inspected for damage. Verify that there are no loose connections.Description of the Problem:The position reports are not received in the office.The Product Link PL102C system depends on several communication links in order to transfer data from the machine to the office.

The cellular network is operational in the geographic area of concern. The cellular coverage is confirmed by clicking the "Status" tab on the Caterpillar Service Tool software screen. A green light icon will illuminate to indicate cellular coverage.
The worldwide network of Caterpillar's computers is passing messages to the Equipment Manager (EM) software.
EM is configured properly and the software is functioning.The Product Link PL102C module should not be replaced without first verifying that the issues mentioned above have been investigated and if needed, resolved. Contact the Service System Support Center for aid in resolving these issues.Every 24 hours, in "Power Mode 1", four position reports and one SMU report are transmitted. Fewer messages are sent in power mode 2 and power mode 3. If there is no position report after moving the machine and the SMU report is received, the unit is likely to be configured correctly.
