Want to use RS232 comms with ethernet module installed

I have an Industruino IND.I/O bottom board on a D21G top board and am using the ethernet expansion port to drive TCP comms to a back end server.  All working well, but now I have to be able to talk to an RS232 (Levels at 5v or 3v3) device at the same time.  I have scoured the forum but cannot find an answer that doesn't use the expansion port.

I am using Ch1-6 on the digital I/O socket but none of the analogue.

Should I use an RS485 to RS232 converter or is there a way to use the Indio?

Hi, indeed an RS485/RS232 converter is the best option; the digital and analog I/O channels cannot be used for serial communication.
