easy enough to figure out. I sometimes have problems with getting the data to download from the device itself.

Could be me, as I have a few serial devices I use on and off with my PC.

You'll need a serial port on your PC (getting the be rare these days) or find a USB-Serial adapter.

edit: only the RR model has the download feature.

Thanks for that. Serial port? Hmmmm... I dunno if my lappy has one or not...
