Chapter 4 Cable Connections and Communication
RS-422/RS-485 Port
The RS-422/RS-485 port is a nonisolated port that supports point-to-point
communication.
The RS422/485 port has integrated 121 ohm termination between the R and R-
signal pair. This value is compatible with RS422 and RS485 electrical
specifications. Additional termination on the PanelView Component end of
communication cables is not required.
USB Ports
The terminals have a USB device and USB host port.
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.
You can use the USB host port to connect a USB Flash drive to transfer
application files, fonts, and images.

Some USB flash drives might not be compatible with the
PanelView Component terminal and might not support file
transfers or firmware upgrades. The 2711C-RCSD memory card
is tested with the PanelView Component terminal to ensure
compatibility.
