User configuration file: T1 - T5

The User Configuration contains the fields T1 - T5 for which the unit is given in counts. How can I convert these numbers to the usual such as meters or seconds? For example I read 19 for the value T1 (Transmit pulse length), which should be 0,11 m (according to the ASCII output in the .hdr file.

Dear Marco Schrijver,

These numbers are instrument timing controller settings and directly related to the hardware design. They vary from instrument to instrument . In general this type of information is not supported, but we are happy to answer any questions you might have regarding your specific instrument configuration.

Hello,

As previously asked: The User Configuration contains the fields T1 - T5 for which the unit is given in counts. How can I convert these numbers to the usual such as meters or seconds? For example I read 19 for the value T1 (Transmit pulse length), which should be 0,11 m (according to the ASCII output in the .hdr file. The measurement device (actually there are 3 of them) is an Aquadopp 2 MHz profiler, mounted vertically. 

Another question is the salinity which is set in the deployment file, and given in the .hdr file. The binary file only gives the field 'AdjSoundSpeed', which in my case gives a value of 16657. The salinity was set to 30 ppt. How is the AdjSoundSpeed used, and how can I convert this to Salinity?

The reason I'm asking is, is that we're starting a measurement campaign of 6 months on several locations in the Western Scheldt (Netherlands), I'd like to have insight in the variables described in the System Integration Manual (and present in the binary file) so I can convert all relevant data to logfiles. 

Best regards,

Dear Marco Schrijver

All relevant parameters are translated to engineering units and listed in the *.hdr file when you convert the binary data file to ASCII.  In other words, there should be no need look at the details of the binary header files. If you are looking to build your own online application, the place to look is the ActiveX library on the WEB site, which will deal with the translation between engineering units and hardware clock parameters.  

I am sorry if we are offending your sense of right to access but we do not provide detailed information about the firmware or hardware design.

Dear Atle,

Thanks for your reaction. I'm indeed building my own application, but I'm  working on UNIX/C  so there won't be much help from the library. I'll use the bin2mat routine instead and work my way from there. 

Best regards,
Marco

Dear Marco,

If you need any assistance please let me know. Our programmer has a lot of experience in working the data files in C.

Best regards,

Sicco
