      Hello,

      I'm not very knowledgeable about communication, so a lot of detail would be much appreciated.

      I want to connect my WeIntek MT8071iP to by UniPi 1.1 without needing a network connection. Is this possible? What are the required cables?

        Hello @wicked,

        an alternative way to read data from the is Modbus RTU utilizing the RS485 serial line. Unfortunately, that only available as a standard feature of Neuron and Axon lines, but not in Unipi1. However you can use any USB-RS485 converter which is available on the market.

          So, I can't use a DE-9 to Rj-11? Is the USB-A on the HMI a RS-485? Is there some guide for this?

            Hello @wicked,
            my colleague meant something like this:

            8cdc4f26-9f26-4016-ac06-5cd9cc9a859d-image.png

            Then you will have RS485 on the Unipi 1.1 and you can connect to the Weintek over DB9. It will act as a additional serial port to the one exposed as RJ11 connector.

            Best regards,
            Martin
