Connecting devices to Edge IO using RS232C

Hello All,
I am trying to connect a device to Edge IO using RS232C.
I am a novice when it comes to communication protocols.
Node-red is disabled.
The device side is listed as connecting with DC2/DC4 handshake.
Do I need to configure anything in this case?

The driver setup screen is shown below.
Baud was mentioned in the manual, so I am sure it is correct.

This looks sufficient. If you haven’t found it already, the guide for RS232 (serial) is here: Using the Serial Driver | Tulip Knowledge Base - Support for Building Operations Apps

Thank you for reply.
Have the serial driver function turned on.

I was looking at the link below.
