VRP Remote Upgrade Procedure
Starting Remote Upgrade
To begin the procedure, ensure that the machine is on and in standby mode with “Smart”
illuminated
All that is required to start the Remote Upgrade procedure is to insert the “Remote Update” SD Card
into the SD Card slot of the Wall Controller. If the system detects that there is no need to upgrade
(all the Software Revisions already match), the Wall Controller will momentarily drop connection to
the FMC (the “Smart” Icon will turn off). After a moment it will recover connection and continue
regular operation.
Tracking Progress
While there is no percentage completion display, there are multiple visual cues to track the
progress of the Remote Upgrade process. The two-digit portion of the screen will show
combinations of numbers and letters to display which stage of the process the system is in, to
display success or failure, or to display an error if one is detected. The update process will take
approximately 20 minutes.
Stage Display
After the card is inserted the WC screen will display a series of letters and numbers. The first to
be displayed is “UP” and the Hourglass Icon. After the system determines that the FMC is OK to
continue the procedure, a “02” will be displayed while the FMC verifies the MCS’s status:
As the procedure progresses, these numbers will change to display each stage of the process.
The highest stage that might be seen is stage 9.
