RS-232C and non-protocol transmision

[pszczepan 2]

Hi I have scale which have DB9 female plug. I used CX-simulator to communicate with virtual PLC and it worked. Now I decided to attach this scale to RS232 Board to CP1H; it has female socket so I had to exchange female plug to male plug in my scale. I used the same pin out and I have framing error - just look my PLC settings and flag A528.03 : What is the problem? - maybe I should exchange wires in my pin out 2(txd) and 3(rxd). Rest of wires are the same as I look at scale pin out wiring? Thanks Pawel
