MILLPWRG2 Recovery Drive and Software Compatibility

  • Due to hardware differences the original MILLPWRG2 console and the current console require different software upgrade paths.
  • Consoles can easily be identified by the color of the front bezel. The current design has a darker grey color than the original design.
    • The current G2 console will proceed to release 5 (R5) and all its service packs.
    • The original G2 console will remain with release 4 (R4) and all of its service packs.
  • To verify your software version, from the DRO screen press Setup. If you have a softkey labeled More Commands you have Release 1 software. If you have a softkey labeled Install Setup press this key.  Enter the password 8891 and press Enter.  The installed software version will be displayed at the bottom left of your screen.
  • Scroll to "Extras" at bottom of page for offline software details, previous release notes, instructions and software.

  • Download and read the release notes for software update instructions prior to updating to any software version.
  • R5 cannot be installed unless you have R4SP4 installed first. If you have previous version of software such as R1, R2, or R3 SPx (release 1, release 2, or release 3 with any service pack) download and install R4 SP4 prior to updating to R5.
  • Due to the enhanced features of release 5, it has become necessary to restructure the console's hard drive. USB Recovery Drive ID# 680480-04 is now included in Recovery Drive Kit ID# 1127022-01 which supports all G2 consoles and all software versions to date or planned for the near future. This new recovery drive includes an option for resizing the control’s hard drive partitions. This must only be performed on current consoles (ID#1113777-NN) that are running software release 4 service pack 4 (R4 SP4). Please insure the console is updated to this release prior to restructuring the drive and installing release 5 (R5). Hard drive restructuring is required on these consoles prior to the upgrade to release 5 (R5).
  • Recovery Drive Kit ID# 1127022-01 can be purchased from your local ACU-RITE distributor.

  • Download and read the release notes for software update instructions prior to updating to any software version.
  • These consoles CANNOT be upgraded to R5 and will continue to receive service packs under the R4 release. Please do not attempt to install release 5 (R5) onto these consoles.
  • System drive restructuring on this original design consoles will cause the console to become un-operational and require in house service to correct the issue. Do not restructure the drive on these consoles.
  • Not all software enhancements will be included in future R4 releases. We will continue to support console ID# 745604-NN with service packs through the R4 released software that will mainly include minor enhancements or fixes.
  • USB Recovery Drive Kit 1201909-01 includes a compatible USB Recovery Drive ID# 680480-03 for original G2 consoles (ID#745604-NN) and should be ordered when replacing a recovery drive for these consoles. This drive does not include the restructuring option, so the unit cannot be restructured accidentally.
