Chapter 7 Terminal Connections
USB Ports
The terminals have two USB 2.0 host ports and one mini USB 2.0 device port.
Figure 10 - USB Ports
The mini USB (type B) device port supports a connection to a host computer
using TCP/IP communication and the USB function RNDIS client driver.
The two USB (type A) host ports support connections to:
• USB keyboard and mouse devices, HID devices, with native device drivers
• Removable, hot-swappable, USB flash drives for external storage
• USB supported printers
• Other USB devices such as modems, cameras, and bar code readers
A vendor specific Windows CE driver is required for all other USB devices. For a
list of compatible USB devices, go to the knowledgebase at the Rockwell
Automation technical support site and search for ID 115072.

Plug a USB device into either one of the two USB host ports on the logic module.
If a USB hub is connected to the terminal, an externally powered USB hub is
recommended. Before attaching devices to a USB hub, check that the power
adapter is connected and powered on.

IMPORTANT
The USB host and device ports are not to be used for runtime operations.
WARNING: Do not connect or disconnect the communication cable with
power applied to the terminal, or the serial device on the other end of the
cable. An electrical arc could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous
before proceeding.
WARNING: USB devices not powered by the USB port must be within
the same enclosure and connected to a ground system common with the
terminal, or the USB devices must be used with a USB hub that provides
galvanic isolation.
