Hi,

I am trying to record a simple serial string to the serial sensor port at 4800 baud.

I can capture it in hyperterminal, so I know it is outputting correctly, and I am fairly confident the wiring (rx,tx, and gnd) are correct.

When I look at the value in the web interface, it says "20 State" instead of serial data.

Here is the configuration of the serial sensor port as a manual channel:

1Serial("$name" )
profile sersen_port bps=4800

and sending the command profile sersen_port gives me this:

DT80> profile sersen_port
[SERSEN_PORT]
*BPS = 4800
DATA_BITS = 8
STOP_BITS = 1
PARITY = NONE
FLOW = NONE
MODE = RS232
FUNCTION = SERIAL
DT80>

Good afternoon adeklerk,

The error you are getting is a time out error.
While you may have the communications set correctly you might not be parsing the string correctly.
What is your data string and how are you parsing each item in the string?

Cheers

Roger

Hi Roger,

Thanks for the response. Do I have to parse out each part of the string? Or is there a way to record the raw data? Here is an example of the data string:

20:52:04.500: $YXXDR,A,4.6,D,PTCH,A,7.3,D,ROLL5B
20:52:04.500: $GPGGA,205201,4703.6643,N,13952.0202,W,2,8,1.2,10.8,M,,,,0D
20:52:04.500: $YXXDR,A,4.6,D,PTCH,A,7.2,D,ROLL5A
20:52:04.500: $WIMDA,30.6285,I,1.0372,B,12.3,C,,,,,,,184.5,T,167.2,M,14.6,N,7.5,M1C
20:52:04.500: $YXXDR,A,5.1,D,PTCH,A,8.2,D,ROLL53
20:52:04.500: $WIMWD,184.4,T,167.1,M,14.8,N,7.6,M6E
20:52:04.500: $YXXDR,A,5.4,D,PTCH,A,8.1,D,ROLL55
20:52:04.906: $YXXDR,A,5.6,D,PTCH,A,6.0,D,ROLL58
20:52:04.906: $GPVTG,17.4,T,0.1,M,1.0,N,1.9,K,D1C
20:52:04.906: $HCHDG,118.7,0.0,E,17.3,E78
20:52:04.906: $YXXDR,A,5.7,D,PTCH,A,5.7,D,ROLL5D
20:52:05.328: $YXXDR,A,6.2,D,PTCH,A,4.8,D,ROLL55
20:52:05.328: $WIMDA,30.6285,I,1.0372,B,12.2,C,,,,,,,184.2,T,166.9,M,14.1,N,7.3,M*11

As you can see, there is a lot going on. I don't want to invest the time in programming the dt80 to parse out each part if I can record the raw data.

Thanks,

Alex

Good morning Alex,

You would be much better off parsing the items you need from the data string and saving those.
Take a look at the FAQ's http://www.thermofisher.com.au/show.aspx?page=/ContentAUS/Manufacturing-Processing/Industrial-Loggers/DataTaker/DataTaker-FAQ/Program-Code/DT80-Range-Code.html for an example.

Ok, that is a good place to start, thanks.

Hi Roger:

I have a question similar whith Alex . I had read FAQ's http://www.thermofisher.com.au/show.aspx?page=/ContentAUS/Manufacturing-Processing/Industrial-Loggers/DataTaker/DataTaker-FAQ/Program-Code/DT80-Range-Code.html example. This example only told me how to record one row.
Now I want record four different rows from one serial sensor,the data example like these:

$GPGGA,205201,4703.6643,N,13952.0202,W,2,8,1.2,10.8,M,,,,0D
$WIMDA,30.6285,I,1.0372,B,12.3,C,,,,,,,184.5,T,167.2,M,14.6,N,7.5,M1C
$GPVTG,17.4,T,0.1,M,1.0,N,1.9,K,D1C
$HCHDG,118.7,0.0,E,17.3,E78

how can I record all of them? thanks

Hi Gavin,

You may detect the first NMEA string for your starting reference as schedule trigger.
Then use continuous parsing for the second to the fourth NMEA string.

Example:
RA1SERIAL"$GPGGA,"
1SERIAL("\m[$GPGGA,]%f[1CV]...." )
1SERIAL("\m[$WIMDA,]%f[11CV]...." )
1SERIAL("\m[$GPVTG,]%f[21CV]...." )
1SERIAL("\m[$HCHDG,]%f[31CV]...." )

However problem may arise if the sequence of NMEA string is not always the same.

Best regards,
Rudy Gunawan
