I have a problem send command with "F001B2FF" TXD but RXD receive data the same command.

The system to read data from controller connect with serial port CJ1W-SCU32 setting Port1 in No Protocal Mode (RS-232C). First i setting end code with "FF" and got data the same command, and change setting End Code to CR,LF but received data the same. Please help me, how to solve the problem? The receive data should be "F001B2xxxxFF".

But i send the command with PC the received data its OK.

Thank you.
