IPm Firmware Revision History

by | Apr 25, 2021 | IPm Advanced Configuration-Group

Note: IPm firmware versions are of the form major.minor.buildnumber. A letter X will be appended in the case of unreleased experimental versions. Other letters may be added in the case of patches or other special versions. As such, releases which are not consecutive are to be expected. Anything in between two releases was an intermediate version on the way to the next release.

IMPORTANT: Firmware versions 4.9 and later only support the following models:

  • ST-IPM-6350
  • VT-mIPM-245-D
  • VT-mIPM-135-D
  • VT-IPM2M-113-D
  • VT-IPM2M-213-D

IMPORTANT: Firmware versions 4.3.174 or 4.9.143 required on models with the new FPGA chip. IMPORTANT: To downgrade from 4.9.152 or 4.3.179 to 4.3.174 or 4.9.143 requires installing DisableAdvancedErrorCorrection.tgz. Please please contact Support before Changing RTU Firmware.
