yokogawa aq6370

[Radioman00]

hi, i ama working on a application which gets optical spectrum data from an Optical Spectrum Analyser (OSA) by Yokogawa, it supports tcp/ip ethernet interface so i have developed a code using labview VIs they have provided(i am a beginner to labView :-] ), following closely with the example VIs they have given to communicate with the OSA. However after much trouble trying to establish a communication, i finally managed to make a connection and then i get error 1074003951, Identification Query failed.

the example VIs also return this error and i have tried to run the program with ID query turned off, but for no avail. Has anyone got experiance with such an instrument? or got more detail on TCP/IP communication via labview/on the error than what NI provide?

thank you very much, i stress the urgency since the rest of my project requires this initial step to be working correctly :S

i have tracked down the error to VISA read on the VI that establishes connection with the OSA and i get error 1073807339 - timeout ... i have used the default timeout value 30000ms and the byte count of 256 that was given with the VIs ... should i change either of the values as suggested by NI? i don't understand why the default values give this error... 

thanks a lot

Hi Asiri,

The identification error is usually generated when you try using an instrument driver that is not designed for the instrument you have.

You should see in the Instrument Open VI that the command *IDN? is sent and the response is then checked. If the response does not match to certain keywords then an error is generated.

Can you tell me what driver you have and were you downloaded this driver from as I can not find the AQ6370 on www.ni.com/idnet These are the only drivers supported by National Instruments and only if the page states the driver is supported.

Hi, sorry i didnt know how to delete a previous question because infact this problem is now solved, it was a error with the firmware of the OSA that caused this, so a simple upgrade worked 🙂 the drivers were downloaded from the Yokogawa (y-link) site and is for the AQ6370 model i am using through ip/TCP connectivity.

again, sorrry for wasting your time and thanks for replying.

Hi Asiri,

You are welcome, in future if you want to delete a post, the best way is just to post the answer to the forum, so others here can use that information to solve any issues they have.

Thanks for letting all the users know the solution to this problem.

Asiri, I've just unpacked a new AQ6370, and I'm interested in getting control through LabView going. Any chance you would be willing to share some of your LabView VI's with someone just getting started?
