Raven XE
24 20080616
Your Raven XE’s full-speed (12 Mbit) USB 2.0 port can be connected directly to
most computers or other devices using a standard full-speed USB 2.0 cable. If the
computer or device you are connecting or the cable is not rated for full-speed, the
modem will communicate at a reduced speed to match. The Raven XE functions
as a device, not a host.
When it is connected to a computer, the USB port should be seen as a COM port
or Ethernet port after the applicable driver is installed.
The Raven XE has a standard mini-B connector.
Warning: The USB port can only be used in a non-hazardous environment.
Indicator Lights
When your Raven XE is connected to power and an antenna, there is a specific
pattern to the lights to indicate its operation mode.
