USB OTG Port

Figure 3-7: USB Micro-A cable connector

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, the

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.
