Serial read not giving an output?

[superomario]

If i run the hyperterminal it says that another program is using the device.....I closed everything even labview though.

Give byte count at read visa as 10 and try. If you not get succeed, try to send some other command from your device manual and see whether the device responding or may be the problem with your serial device.

[superomario]

No luck with 10, and those are the only two commands in the manual. I have attached the entire manual the secion on comunication is in chapter 6.

I did just get this error however

VISA:  (Hex 0xBFFF0015) Timeout expired before operation completed.

from the attached VI. 

[shjukheter]

Drag the close Vi out of your loop and give the time 2000 between you write and read visa. I would recommend you to look the basic example and play around in that example. I have posted that example in this thread.

I am getting error -1073807339 the timeout read error. what does this mean? 

[Dennis_Knutson]

The error means exactly what it says. Your read timed out. Your read timed out because you are not sending the correct string.

Have you been paying any attention at all to what people have mentioned about a termination character? Append a CR (Carriage Return) to the string you are sending.

[superomario]

I did add the CR line , see the attached aa.vi. but it still stalls at the read funciton.

and i found this program on the forum, but it returns back 0 bytes when i send it a TS command. 

[superomario]

Ok when is send the device the command TS, i get a return count of 2. IN the spec manual it says 

"When communication terminal sends “TS” command to the OX400, OX400 will feed back datalogging packet periodically (approx. 200 ms.)" 

So how do i let labview know to just keep the port open after this and keep reading it? I thought that was what i was doing with the read function but it isnt working. If i send the string with the stop command in it as well as you have all been saying . wont i just get one value instead of a continuous read of the display?
