USB Interface
The SEL-3031 uses a standard USB Type-B interface for the management port. The
USB interface is used for settings management, initial radio installation, and reporting
data from long-term radio statistics. The management port may be used while the
SEL-3031 is in service without disrupting the radio communications. To use this
interface, plug a USB Type-B cable into the radio and plug the other end into your PC.
This will automatically prompt your PC to install a USB-to-serial driver that creates a
virtual serial port. The virtual serial port needs to be set to 9600 bps, 8 data bits, 1 stop
