Module's working mode can be set as needed, we try my best to let the user work become simple, all did
not open advanced parameters, if you have special requirements, please contact us .
You
can set the work mode, the module IP and port, subnet mask, gateway, serial port baud rate, module
port, destination IP and port , c an be set through the serial port or network port are two ways to setup software
(USR-TCP232-Setup) .

O nce in configure mode, the UART parameter change to 9600bps,n,8,1, and a ‘ U
’
ascii character is
send out to ensure the control MCU that in the configure mode. If the 24byte command has effect , a ‘ K
’
ascii
character is send back to control MCU. If configure command format error, an ‘ E
’
character will be send back
to control MCU. If the error is the checksum not match , the 1byte right checksum will be send back to control
MCU also.
