Controlling the ACU 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 ACU. The message to the ACU thereby is coded into the URL as a CGI form parameter. The ACU replies a one line document of the MIME type ‘text/plain’.

The document name for remote control is /rmt , hence (assuming the ACU is listening to the IP address 10.0.0.1), requesting a document with the URL

http://10.0.0.1/rmt?blev=?

Will let the ACU reply the actual beacon level in a one line text document:

blev=-52.31

This way all parameters may be queried or set, you may use your favorite web browser to try out the remote control of the ACU manually.
