Not sure what you are asking me.
1.- I have a DB9 to DB9 for the RS232,
- I checked the cable with a multimeter and also using hiperterminal (putty) to check the laptop this worked fine.
- With this cable i used the pins 2,3,5 and regardless the connection of pins 2&3 (i swapped this two) the communication didn’t work.
2.- I have another cable (specific for communication RS485), where the DB9 for the anybus and free wires to connect to the RS485 to RS232 converter.
I also tested the RS485 to RS232 converter alone at 38.4kbps using two laptops and it worked fine.
So in this part, we already know that the communication worked up to 9.6kbps, the difference between this and the 38.4kbps is the dip switches. the laptop worked, the converter worked and the cables worked at 38.4kbps when a test them by separate.
So, it seems that what you are asking i already did it.
Let me know thanks
