Z-Wave US module with adapter

[MarkHaysHarris777]

I have the Z-Wave US module that plugs into an adapter that plugs into the Pi-2 bus.

This is probably answered somewhere but my searches are saturated with irrelevant Z-Wave EU information and I'm lost.  How do I use the US module?  Is it hanging off a serial port?  What software can I use to get it working?

Thanks.

Yes, the Z-Wave module is accessed via uart(2)  /dev/ttyS2   (  it is a serial device  )

You can talk to the module via serial protocol manually,  and you can use a serial software package to talk to the module ( point the software at /dev/ttyS2 )

( /dev/ttyS2   uart(2) is on the PI bus )
