InstaCal (Version 6.73) keeps auto-changing thermocouple AI channel settings

[Brendan]

I am using a USB-2416.  In InstaCal, I am configuring Channels 12-15 for Type K thermocouples.  After setting the proper configuration for the channels, the channel settings are being changed/reset back to Type J.  Sometimes, the channel types are changed from thermocouple back to voltage.  How do I set and then maintain my channel configurations?  Thanks.

Hello @Brendan.

What OS are you using?

What are the firmware versions shown in InstaCal?  The current firmware is available here:  https://www.mccdaq.com/firmware.aspx

Please detail your steps to reproduce the issue and include screen captures.

I was able to configure the channels on one Windows system and connect my USB-2416 to a different Windows system, which showed my channel updates.

Hi Fausto.

Screen captures are attached (the ones that I have right now).  I can get more info the next time I am in the lab.  Thanks.  Do these tell you anything?

Hello @Brendan.

Thank you for the screen captures.  The factory serial number is corrupt.  Are you able to update the firmware via InstaCal, after download the current driver?  Is there a serial number label on the backside of the module?

Hi Fausto.

Updating the firmware seems to have solved the problem.  Will the corrupt serial number cause any issues?  I have not noticed any.

Thanks.

The factory serial number should not have a '?'.  Did the serial number change, after the firmware update?  Are you able to use the USB-2416 with your application?

Hi Fausto.

I do not have any details about when/how the serial # changed.  Everything seems to be working at this point.

Thanks.
