The format for the network message is: 'http://ip.address:port'. For example,
http://192.168.111.103:8032.
The format of the output string can be chosen from the drop-down menu. Four message
format options are available, Default, Format01, Format02 and Format03.
After modifying or creating a new subscription, click the 'update' button and authorize
the changes. This will change and store the settings and implement the subscription with
immediate effect (no system reboot is required).
Default message format
The Default format starts a new line for each parameter in the subscription. The time used
in the Radac format is Unix Epoch time in milliseconds (UTC time in milliseconds since
st
00:00:00 on the 1 of January 1970). Each line in the Default format ends with a Line-Feed
character (char10). When a parameter is disapproved or not available the string 'NaN' is
inserted instead of the actual value (NaN stands for Not a Number). An example of the
output strings in the Radac format is:
time=1157359800206;sensor=radcan;H1=-319.9429cm;
time=1157359259847;sensor=radcan;Hm0=1.2517135cm;
time=1157359860268;sensor=radcan;H1=NaNcm;
Format01 message format
The Format01 message, formerly called the SESAM format, used by the Dutch Ministry
of Infrastructure and the Environment (Rijkswaterstaat), is only defined for the heave and
the 10 second mean (H parameter). It consists of 8 character lines (Line-Feed character +
status character + sign character + 4 character value in cm + Carriage-Return character).
For a regular message the status character is a space. If an error occurs the status character
becomes a letter A. An example of the output strings in the RWS format is,
