Serial com Dropsense potentiostat mu-200

Has anyone experience in setting the serial communication with the Dropsense mu-200 potentiostat?

I'm trying to write a com program in Labview using the file given me by the company, but I'm not sure how to read the current...

Hi

you need to send commands to your device via serial from LabVIEW

you find some examples for LabVIEW 2012:

National Instruments\LabVIEW 2012\examples\instr\smplserl.llb\Basic Serial Write and Read.vi

Serial Communication General Concepts

Did you first verify your Serial Port using Hyperterminal?

Thanks for your reply,

yes I've set up the serial com using a subvi that use VISA write and VISA read and I do get replies from the apparel, so the port is ok,

however with the attached serial protocol I've some doubts regarding the current recording, so I was looking if someone is doing the same serial com somewhere else...

Ok, I've found the issue, I was reading a not large enough bit number while reading from the instrument buffer,

many thanks,

Davide

Hi,

you are welcome 😉

FYI : you can read more than the default 4096 bytes off of a serial port. You simply need to increase the buffer size that is by default set to 4096 bytes. This is achieved by using VISA Set I/O Buffer Size.vi which is located in the Functions palette under Instrument I/O»VISA»VISA Advanced»Bus/Interface Specific.
