To talk ASCII, you would use Freeport mode. XMT and RCV are the commands. There is a little bit of setup involved. The topic "Understanding Transmit and Receive" in the MicroWin Help is a good start.

if output analyzer is rs485 db9 port i can see pin of s7200 in manual and direct conect (not use PPI adeptor)?

Yes. Just connect directly from the DB9 to your device as the ports are RS485 signal levels. Use Freeport mode for the port in question.
