Interfacing machine with RS232


I have machine where the only option for communication is RS232.

I would like some advice on how to establish communication between a UR5e and the machine. One of my thoughts was to use a single board computer (maybe a Raspberry PI) and the connect some of the DIO’s to the robot control box.

I also thought about using Ethernet or USB between the single board computer and the UR control box, but I am not sure about how to do so?

Any who has some documentation/advice about how to do the interfacing?

Is there a commercialized option on the market maybe?

Best regards Alexander


This might be an option.

You could also consider a product like this to directly interface with the RS232 device, in addition to Phil’s suggestion:
