PROBLEM
New software for Product Link is now available. The new 3303408/">330-3408 (PL121)Communication Software Gp replaces the former 311-8377 Communication Software Gp. The new 3303409/">330-3409 (PL300) Communication Software Gp replaces the former 311-8375 Communication Software Gp.
The new software for Product Link 121 has the following enhancements:
? Improvement to the operating system for stability of flash memory
? Improvements to the GPS algorithm
? Improvement to the registration process of the PL321 when the PL121 was previously registered as a PL121 stand-alone
? Event messages will now appear in PL121 Message Queue in CAT ET. This improvement will signify "time/geo-fence" alarms that were being sent.
? The PL121 will now send time fence alarms when the engine is started outside of the time fence. Also, the PL121 will send only new "time geo-fence" messages when the messages occur. The PL121 will not send repeated alarms that were already active. Consecutive day alarm messages will still be provided in the daily status message.
? Product Link will now accurately detect that the keyswitch has been switched to OFF.
? The radio will now shut down normally even if the antenna is disconnected. The radio will also shut down normally even if there has been no satellite communication since the last power-up.
The new software for Product Link 300 has the following enhancements:
? PL300 software now reports combined fuel usage for machines with dual engines.
? PL300 software minimizes the chance of receiving "Last Known Position" status when the Product Link is in Power Mode 2 or Power Mode 3.
? PL300 software will detect a keyswitch OFF more promptly in order to initialize the sync clock arbitration process again. When the keyswitch is turned from OFF to ON, this enhancement will avoid temporary SYNC clock master changes.
? Improvements will ensure that the Service Meter Hours (SMH) for Product Link do not reset to zero.
? Improvements will ensure that the Product Link does not deregister itself.
? PL300 software will now properly use the Engine Operating Status, running or not running, when the keyswitch is OFF in order to determine whether or not to increment
the SMH.
? Administration messages will not be sent before the module is registered.
