I have a device that transmits data using 3964R. This is a protocol that was designed by Siemens for bi-directional data communication. I do not see it available under the list of OPC UA device drivers on the gateway. Does anyone know of a method to connect to a 3964R device? ---

Is it a Siemens S5 or something else? [https://www.kepware.com/en-us/products/kepserverex/drivers/siemens-s5-3964r/](https://www.kepware.com/en-us/products/kepserverex/drivers/siemens-s5-3964r/) ---

It is a Bunting Magnetics AMD05 metal detector. The physical layer is RS232.
