Transparent Mode
USR-WIFI232-A/B/C modules support serial interface transparent transmission mode. The benefit
of this mode is achieves a plug and play serial data port, and reduces user complexity furthest. In
this mode, user should only configure the necessary parameters. After power on, module can
automatically connect to the default wireless network and server.
As in this mode, the module's serial port always work in the transparent transmission mode, so
users only need to think of it as a virtual serial cable, and send and receive data as using a
simple serial. In other words, the serial cable of users’ original serial devices is directly replaced
with the module; user devices can be easy for wireless data transmission without any changes.
