lakeshore 340

[krishna12345]

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.
