Peripheral Connection
PanelView Component terminals have a USB host port. You can power USB
peripherals directly from the PanelView Component terminal. If the USB
peripheral is not powered directly from the PanelView USB port either:
• install the USB peripheral in the same enclosure as the PanelView terminal
and make sure it is connected to the same ground system.
• connect to the USB peripheral through a galvanically isolated hub.
TIP
When receiving updated help files, you may have to clear cache in
your browser before the new help files display.
View the PanelView Explorer online Help for detailed instructions.
ATTENTION: Removing the USB flash drive or SD card, from the
PanelView Component terminal, while a firmware upgrade is in process,
could corrupt the firmware and make the terminal unusable. Take
precautions to prevent the USB flash drive or SD card from being
accidentally disconnected. Also, do not power off the terminal while a
firmware upgrade is in progress.
ATTENTION: USB hubs can produce unexpected behaviors and as a
result are not recommended.
