UniPi 1.1 and WeIntek interfacing
-
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:
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,

Thank you for the clarification, @Martin-Kudláček .
