Facts and Changes

Causes and Fixes
 
An issue was discovered with the Firmware that led to this fault. It was corrected in Version 1.0.24.4 of the firmware.
 
There is considerable confusion regarding the identification of the firmware of the PRM. The only way to identify the current version is to use the DTM Browser in UnityPro to connect online to the PRM and read the version directly from the unit via the Device Menu->Diagnostics. If found to be other than 1.0.24.4, it should be updated
 
The update is performed using the DTM Browser but some preparation may be  needed. The file needs to be renamed "PRMOS.bin" if not already done. No exceptions.
 
Using the DTM Browser:
 
  1. Right Click on the Instance and select Device Menu ->Download Firmware.
 
Note that the PRM will reboot at the end of the transfer.
 
 
  1. After the Reboot confirm the version has changed using the Diagnostic function.
