How to connect QL355TP Power Supply

[satheeshvelu]

Hi Graeme Smith,

Were you successfully automated QL355TP? I'm trying with Python & LabView. No success so far. Could you please share your knowledge how you brought it up?

Thanks,

Hello, I have the same error, I can send commands and I managed to set voltages, or voltage steps, etc. but I can't read the data backwards as with the * IDN command ?. Said to make a driver work, but I don't know how.

Hi,

I have made it work. You need to give enough delay for the data t be available on the UART. Will share my code on Monday.

Hi,

I have given 20ms delay to read the data.

serialPort_PSU.WriteLine("*IDN?");
Thread.Sleep(20);
PSU_receiveBuffer = PSU_receiveBuffer + serialPort_PSU.ReadExisting();

You can refer to the attached file for complete code. It's written in C#
