Guys I want to input 5 analog signals into DT80, combine the 5 analog values into one string in DT80, maybe add some NMEA symbols like "$" and "WMD" into the string, and then output the string through RS232 host port or sensor port.

So DT80 acts something like a analog to RS232 converter. Is this possible?

Advance thanks.

Good morning Orange,

Yes you should be able to but you won't be able to do the check sum at the end of the line. If you don't use DeLogger you can set the DT80 to CSV format by using the commands

/h/R/n/c/u P22=44 P24=13 P33=0

You can then build up an output to match the string using the channel data. For things like time simply add T in the correct place in the string and use the FF option to set the number of decimal places.

The only thing you won't be able to calculate on the fly is the check sum. If the receiving equipment can be set to ignore the check sum then it will work.

Cheers,

Let see if I got it clear:

This means that if I just hook up hyperterminal to DT80 host port I can see a NMEA ASCII data string. I don't have to hook up a dataTaker software like Delogger.

This project is to combine 5 weather sensor analog inputs into one serial string and output it to a external autopilot unit.

Good afternoon Orange,

Yep. Any terminal program can be used to program a dataTaker. DeTransfer is a terminal program we wrote that has extra features to support the dataTaker range.

The main trick is when you connect send the commands /E/M/R to get the dataTaker to respond and /e/m/r before you disconnect. This will give you full control over the dataTaker and you can change the output text format to suit.
