Read new line of returned message

[Angelia]

Hi,

I am new to labview and I am trying to get the return message from an instrument which is three lines long, but only one line gets displayed. How can I read past the carriage return?

Thanks.

Try this

When you use VISA WRITE  to send command, give bit delay & use BYTES AT PORT FUNCTION and wire the output to VISA READ. You must read all the information which the device sends.

Kudos Appreciated :manvery-happy:

Check the Termination char setting for comport

http://zone.ni.com/reference/en-XX/help/371361G-01/lvinstio/visa_configure_serial_port/

termination char calls for termination of the read operation. The read operation terminates when the termination char is read from the serial device. 0xA is the hex equivalent of a linefeed character (\n). Change the termination char to 0xD for message strings that terminate with a carriage return (\r).

Or just read it 3 time one line at a time to get all the data. Set the number of bytes to read to something larger than you will ever get back on each line.

Your main problem is that you need to set the Enable Termination Character input of the VISA Configiure Serial Port function to false.With it enabled, a read will terminate as soon as the termination character is detected.

I tried to set Enable Termination Char to OFF, but the same problem still exists.

How should I read one line three times? For loop apparently doesn't work.

WHich instrument are you interfacing, try searching the labview drivers in here might help you.

Disabling the termination character or a for loop should work. Attach your code so someone can see exactly what you have done.
