Can I use the example image instead of the industrial os on the IOT2050 advanced FS07 and still be able to use the RS485 for modbus. Or do I need to use the Industrial OS and if I have to use that what do I set on the Setup time and Hold Time?

And another thing, what is the format and how to write the setup and hold time in the service stick when Im in industrial os to turn on the RS485 port.

If im using the serial port on the IOT2050 should I use the s2 or USB0 this is not a usb to serial adapter

what setup and hold time need I to use with connection settings 19200 baud, 8 data bits, 1 stop bit, no parity on Modbus RTU on a weather station ws800-umb I have 2820 microseconds right now but getting a timed out.
