USB Ports
The terminals have a USB device and USB host port.
USB Host Port
You can power USB peripherals directly from the PanelView 800 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.
You can use the USB host port to connect a USB Flash drive to transfer
application files, fonts, and images.
ATTENTION:
The USB device port is not intended for Customer use.
WARNING:
The USB host port is intended for temporary local programming
purposes only and not intended for permanent connection. The USB host port
cable is not to exceed 3.0 m (9.84 ft).
WARNING:
If you connect or disconnect the communications cable with power
applied to this module or any device on the network, an electrical arc can occur.
This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
WARNING:
If you connect or disconnect the USB cable with power applied to
this module or any device on the USB network, an electrical arc can occur. This
could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
ATTENTION:
Removing the USB flash drive or microSD card, from the
PanelView 800 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 microSD card from being accidentally
disconnected. Also, do not power off the terminal while a firmware upgrade is
in progress.
USB hubs can produce unexpected behaviors and as a result are not
recommended.
