For above networking, USR-WIFI232-A/B/C module works as STA
（
Firmware is Z-Version
）
,and
module configured as bridge mode. When module connect to AP, all devices connected to
module Ethernet interface will get assigned IP address from AP (For example: 192.168.1.101).For
module works as bridge mode, it can be treated as a transparent device and PC1, PC2 can
communicate without any limit. But in this networking, USR-WIFI232-A/B/C module needs assign
a static LAN IP address (For example: 192.168.1.10) if module also needs communication with
AP or configuration through web page.

Auto- Frequency Function
When module works as STA, USR-WIFI232-A/B/C will adjust its wireless channel to keep the
same channel with associated AP and connect in.
When module works as AP and USR-WIFI232-A/B/C enable Auto-frequency function, then when
module boot up, it will select the best wireless channel based on surrounding environment.
