Lakeshore transmitter 240-8p not responding through USB cable, but it is communicating through profibus cable. When we connect USB cable to lakeshore transmitter through measurelink software, it shows error, and communication is not possible through USB cable. But when we check the temperature values in SCADA( through profibus ), it shows actual temperature values.
This is the problem, i need your help to resolve the problem. Thanks in advance

First of all thanks for reply.
As far as COMM port is concern, YES port is configured in device manager and same is reflected in measure link software. But still it shows error message after few seconds "device is disconnected try again later".

Thank you for sending the screen shot showing the error. I will assume that clicking on the connect button will not reconnect MeasureLINK to the Model 240. If that is the case, I would like for you to try connecting to the Model 240 using an external Terminal Emulation program like Hyper Terminal or Tera Term. If you can send an email to [email protected], I can send you the configuration information for Tera Term or Hyper Term if you can use either of these programs.

I followed the step as per guideline given in your document. But still issue is not yet resolved. however, communication has been established through tera term . Serial no. info as per doc was displayed as we write *IDN? (as per
Three screenshot are attached 1. baud rate setting (device manager) 2. successful serial information displayed through tera term 3. error pop up message when tera term software was open in PC
when we close tera term software, if we try to connect measure link software then it connects for few second and automatically disconnect and same error pop up message (disconnect) comes which we have told you earlier
In this way, we can receive information through tera term but issue with measurelink software is not resolved so far. We kindly request you to needful to resolve this issue.

Have you tried to uninstall and reinstall the MeasureLINK Application? Communicating with the Model 240 using Tera Term confirms that the USB Port is operating correctly so the issue seems to be between the MeasureLINK application and the Model 240. Also, please confirm what COM Port you have assigned as I see two different ports in the screen shots you have provided.
Hi...as per my knowledge Bad or defective Thunderbolt data cables can cause many issues with Apollo / UAD devices. If your problem persists after performing the procedures listed above, we recommend replacing your data cable Thunderbolt to eliminate that as the cause of the problem.
