24VDC Power Hub 3500 Operator Manual
When the storage device is full, no more data will be logged. This is due to the nature of Sqlite (a
software library and file type) files. Removing data from the Sqlite database doesn’t free up usable
disk space, and because of internal fragmentation, it doesn’t guarantee more data storage.
If the Power Hub is connected to the internet (Tech Port) past and current data stored on a
microSD card can be uploaded to VRM Portal (See Remote Monitoring). If the internet connection
is intermittent data stored on the microSD card can be automatically uploaded to the VRM Portal
each time the connection is reestablished. Instructions for accessing the VRM Portal are provided in
Remote Monitoring below.
If the Power Hub is not connected to the internet, the user can upload the data backlog manually to
the VRM Portal by using the following protocol. The first step is to use the Settings window to eject
the storage; don’t just remove the SD card (Settings > VRM online portal > Micro SD / USB). The
storage device can then be removed from the user interface and inserted into a computer or laptop;
the data file on it can be uploaded on the VRM Portal with the ‘Upload CCGX File’ option.
It’s important to know that when the micro SD card is reinserted, the existing buffer—including its
data—is used again. This allows for removing the micro SD card temporarily for whatever reason,
but this also means when the data file has been uploaded to VRM, it needs to be renamed or cleared
from the micro SD card before reinserting, otherwise the data will be transmitted again, sooner or
later, online or offline.
MicroSD Card Formatting
Micro SD cards must be formatted as FAT12, FAT16, or FAT32 file systems—not as exFAT or NTFS.
SD- and SDHC-type micro SD cards of 32 GB capacity and smaller are sold containing FAT12,
FAT16, or FAT32. They can be used without a problem, unless they are subsequently reformatted to a
different file system.
SDXC-type micro SD cards with greater than 32 GB capacity are often formatted with exFAT and
therefore cannot be used with the user interface without reformatting and possibly repartitioning.
Remote Monitoring
When the Power Hub is connected to the internet using the Tech Port, both current and historical
performance data from the Power Hub can be monitored remotely. The information provide by the
VRM Portal and how to use that information is describe in Performance Remote monitoring requires
access to the VRM Portal. Instructions for accessing the VRM Portal are provided below.
Getting Started
The process is straight forward and self guiding. First, create a VRM user account. And after that
the installation, needs to be paired with that user account. It is possible to pair one installation to
multiple user accounts.
Requirements
• A computer connected to the internet
• The VRM Portal ID, which uniquely identifies your system
• Power Hub LCD user interface: The VRM Portal ID can be found in the menu Settings > VRM
Logger. It looks like this: be300d83ff04.
