Firmware 1.1.1.14

Last Updated: 12/2006

NOTE for TFTP/HTTP Firmware Upgrade:

1. When the BT200 boots up, it will send TFTP or HTTP request to download configuration files.

There are two configuration files, 1) “cfg.txt” and 2) “cfg000b82xxxxxx”, where “000b82xxxxxx”
is the MAC address of the BT200 .

2. These two files are for initial automatic provisioning purposes only. If using a normal TFTP or

HTTP firmware upgrade, the following error messages in a TFTP or HTTP server log can be
ignored.

• TFTP Error from [IP ADRESS] requesting cfg000b82023dd4 : File does not exist

• TFTP Error from [IP ADRESS] requesting cfg.txt : File does not exist
