Is this a laptop that you are using? If so, ditch it and use a actual desktop with a serial card installed or use the native one if it has it. You'll thank all of us later on.

No good or revelent advice here as the device has its own spc to usb converter that must be used.

Besides there is no reason USB to serial converters on a laptop would function any differently than a serial card in a desktop computer.

I will just say that I have had a lot better luck using PCI(e) serial ports than USB-Serial adapters.  But, yes, irrelevant to the current discussion.

Sorry for the delay on the reply I have been out of town. I have set up the caliper and am trying to get the data however I think I may be missing a step. For the caliper to send the data I need to reuqest it by sending any character, can I do that through visa write?

Thanks

Did you read the manual?  You get the caliper to send the data by pressing the IN/mm button.  The caliper will not recieve any commands through the serial port.

Yes, pressing the in/mm button is a way in which it knows to send data. however there is a way to request data from the caliper without pressing the IN/mm button. there are programs such a winWEDGE that request the data from the caliper by sending any character on the keyboard.

Then the manual should talk about that as well.

If that is the case, then yes, you use VISA Write to send a character out of the serial port.
