Thanks - just been soldering up the connections from other web site
info when I saw your post - saved some debugging!  So I've now got
this step sorted and data coming in on the usb/com port.=20=20

For anyone else, you will (probably) need a Windows driver too -
available here:

http://www.ftdichip.com/Products/EvaluationKits/TTL-232R-3V3.htm

I seem also to have the 'basic' 2400 bps model without historic data -
no info either on software version in the msg.  But it's sending the
power usage info through nicely so that's fine.=20=20

Time to do a bit of playing with xAP.

Regards

Richard
