Installing and Activating AirLink GX400

USB OTG Port

Figure 3-6: USB Micro-A connector cable
The CPU OTG port operates in device mode; when the port is unused, the AirLink
GX400 operates in device mode. If a Micro-B plug is inserted into the port, AirLink
GX400 operates as a self-powered device: it will not draw any current from the
USB. If a Micro-A plug is inserted, the AirLink GX400 can operate in host mode
and supply power to the device that is plugged into. At this time, however, USB
host capability is a future ALEOS enhancement.
Your AirLink GX400's high-speed (480 Mbps) USB 2.0 port can be directly
connected to computers or other devices using a standard USB 2.0 cable. If the
computer or device you are connecting or the cable is not rated for high-speed,
the device will communicate at a reduced speed to match.
When it is connected to a computer in device mode, the USB port should be seen
as a COM port or Ethernet port after the applicable driver is installed and
configuration has been enabled. The port is, by default, a virtual Ethernet port.
