1.2 BDI Configuration
As an initial setup, the IP address of the BDI2000, the IP address of the host with the configuration
file and the name of the configuration file is stored within the flash of the BDI2000.
Every time the BDI2000 is powered on, it reads the configuration file via TFTP.
Following an example of a typical configuration file:
