Controlling the radiometer through the network is done by means of HTTP GET requests. Setting parameter values or querying readings or settings, all is done by requesting HTTP documents from the radiometer. The message to the radiometer thereby is coded into the URL as a CGI form parameter. The radiometer replies a one line document of the MIME type 'text/plain'.
The document name for remote control is /rmt , hence (assuming the radiometer is listening to the IP address 10.0.0.1), requesting a document with the URL
http://10.0.0.1/rmt?aat1=?
will let the radiometer reply the actual atmospheric attenuation in a one line text document:
aat1=0.42
This way all parameters may be queried or set, you may use your favourite web browser to try out the remote control of the radiometer manually.
