CP1L Serial TXD Data Error

1 post in this topic


I have a problem with serial communication (no protocol) using rs485 module, the received data is error.

I'm using CP1L CPU, CP1W-CIF11 module as transmitter, and USB to RS485 converter as receiver.

When I check the received data on PC, it's incorrect (bit error?). I just send 2 bytes data, 0x61 ('a') and 0x62 ('b').

My configuration: DIP switch CPU 4 = off, DIP switch CIF11 1 to 6 = on,on,on,off,off,off, 2 wire RS485.

(I also attached the program and settings)


Could you help me to solve this problem?
