How to configure the "RTU2" port for RS485

Thank you, working!

Oh Undecided , I noticed that if you enabling RTU2 for Modbus over RS485 my TCP/IP devices (also modbus) lost communication. Do you have any idea why this is happening?

My configuration:
TCP/IP: 2 devices (Modbus TCP/IP, port 502)
RTU1:    8 devices (Modbus RTU, 9600bps)
RTU2:    1 device   (Modbus RTU, 115200bps)

PS: TCP/IP + RTU1 working fine.
