AllReferenceSpecial Instruction, REHS2368, "Installation Procedure for Product Link PL522 China (Cellular)"New Software is now available for all Cat® products with the Product Link 522 China system. The new software contains the following improvement for the 376-4616 Communication Electronic Control Module (PL522 China) system:
Addressed issue where Engine OFF/ON status changes every few seconds on machines where Product Link is using R-Term to determine engine operation.Note: To obtain the full benefit of the improvement, both the radio and the gateway software must be flashed. It is important to submit a field support case to have the Radio flashed over the air after the Gateway software has been downloaded and installed.The new software part number is listed in the Table 1.
