USB Port

Warning:
Do not use the USB port in a potentially explosive environment.
• Complies with USB Version 2.0 for high speed operation
• Can be dynamically configured to operate in one of two modes:
• Virtual Ethernet Port: The LS300 behaves as if the PC were connected to
an Ethernet port, allowing access to the Internet and the LS300's internal
web server. This is the default setting.
• Virtual Serial Port: The LS300 behaves as if it was connected to a standard
serial port. The primary use of this interface is for the AT command line
interface of ALEOS and for diagnostic access to the radio module.
Note: By default, the USB port is configured as a virtual Ethernet port.
A Windows driver must be installed on the PC in order to support USB use. The
drivers are available for download at source.sierrawireless.com.
The ALEOS Software Configuration User Guide contains the details of USB mode
configuration and driver installation.
We recommend you:
• Use a USB 2.0 cable
• Connect directly to your computer for best throughput.

Ethernet Port

10 Mbps
• Auto-crossover support
• Auto-sensing detects the speed of the connecting device for 100 baseT or
10 baseT

Serial Port

• 9-pin serial port connects directly to most computers or other devices with a
standard serial straight-through cable
Note: If you have a DCE device, you need to use a null modem (cross-over) cable.
• Used for device configuration and debugging.
• Complies with the EIA RS-232D specification for DCE equipment
