Connect only externally powered USB hubs to the terminal that are USB 2.0
compatible. Before you attach devices to a USB hub, make sure that the power
adapter is connected and powered on.
USB Cables
Use only high-speed, USB 2.0 certified cables for error-free transmissions.
Insert an SD Card Only use a SD™ or SDHC™ card to load troubleshooting profiles and to save
troubleshooting logs. For a list of cards recommended by Rockwell Automation,
see
Table 6 on page 18 . The SD cards are hot-swappable; they can be inserted and
removed while the terminal is powered on and in use.
The SD card slot is accessible from the inside or back of the panel when the
operator terminal is installed.
To install an SD card in the card slot, follow these steps.
1. Verify that the SD card is locked or unlocked according to your preference.
• If unlocked, the terminal can write data to or read data from the card.
• If locked, the terminal can only read data from the card.
ATTENTION: USB devices that are not powered by the USB port must adhere to
the following:
• The USB device must be within the same enclosure as the terminal.
• The USB device must be connected to a ground system common with the
terminal or used with a USB hub that provides galvanic isolation.
• The USB device port is not for runtime operation.
IMPORTANT The terminals have not been tested with USB 3.0 cables. We recommend only
the use of USB 2.0 certified cables.
WARNING: Explosion Hazard
In hazardous location installations, if you remove or insert an SD card while the
power is on, an electric arc can occur. An electric arc can cause an explosion in
hazardous location installations. If the terminal is installed in a hazardous location,
do not remove and insert the SD card unless power has been removed or the area is
known to be nonhazardous.
