lakeshore 340

Hello,

           I am trying to interface LakeShore model 340 temperature controller. When I'm writing commend *IDN?,it's showing '\SSY<]_TU\340<333333<042304' instead of 'LSCI,MODEL340,123456,02032001'.When I'm writing KRDG? A ( Query Kelvin reading for input A) it's showing ;299>667U;0 instead of 299.667K.

please help.

Thanking you.

Are you using the driver at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=01613BBF62F03959E0440003BA7CCD...

I'm not using instrument driver. I'm attaching a picture of front panel.

Use the driver. At least look at it for reference. I believe you need a termination character for that old device.

I have tried by using instrument driver  but it is showing error -1074003951 now. I have read about this error from forum and when I ignore the initialization then it's showing another error.Preveously, this instrument  was showing properly all the commend response.Now it is showing this kind of format. I can't figure out it's problem of Labview program writing or instrument settings.

thanking you.

Previously, you were getting the exact same error according to your first post. If you are getting the same response to the *IDN? query that you got on your code, try it in MAX.

Did you get an answer to your question? I looked and I did not see an answer. I am new here so I might have missed it.

Did you get it resolved? Do you knew how I can get a library or a programmer's guide for the Lakeshore 340? or the commands?

Thank you

The manual is here - LakeShore 340

It looks like the problem was the user did not set the instrument communication termination properly.  The manual explains how to do that on the instrument.

Hope that helps,
