A02YYUW RS-485 Example

I have been using the UART versions of the A02YYUW Waterproof Ultrasonic Sensors for years.  Recently I purchased two more but discovered I had purchased the RS-485 versions.  Unfortunately I cannot seem to find any sample code for the Arduino platform for reading this sensor.  I have tried every library and sample for other sensors I could find to no avail.  Is there sample code somewhere that I can reference?
