Cable Connections and Communication Chapter 4
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.
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 micro-SD 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 micro-SD 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.
