I am using datataker DT80G with labview driver.
However, I'm facing a trouble. As I use DT8x ReadRealTimeAcquisitionData VI, I cannot avoid the Program change message. If I use DT8x ReadLineFromDataTaker before DT8x ReadRealTimeAcquisitionData VI, I can avoid the prgram change message for awhile but after a period of stable running, it will read program change message instead of the data returned.

I don't have any clue why did it goes wrong like that. Could you provide some help. I can send you my code for review.
Contact me at phuong.tranminh@vsl.com

Many thanks.

Good morning phuongvsl

You need to turn of message returns by sending /m to the DT80

Two VIs you will be interested in, are the following.
DT8x SetDataReturnMode.vi

For the input
data return mode: sets the data return mode of the dataTaker
realtime - the dataTaker will acquire data in realtime mode, returning realtime data (/R).
historical - the dataTaker will acquire data in historical mode, not returning realtime data (/r)
And the VI
DT8x SetFormatMode.vi

For the input
format mode: sets the format mode of the dataTaker.
Fixed - the dataTaker is set into fixed format (/H) mode.
Free - the dataTaker is set into free format (/h) mode.

Cheers

Hi phuongvsl,

You can also send any command, such as /m, using the vi "DT8x WriteLineToDataTaker.vi"
This VI is listed in the low level palette.

More information is available online, as well as the help files.

Good luck,

Anthony
