Hello, someone already managed on the node-red communicate via rs232 (usb) and read the temperature data in keithley 2700 and send it to a sheet (excel). Communicate via rs232 (usb) to the Infratek 106A and read the power, voltage, current and send it to a sheet (Excel).
The problem is to get these devices to communicate via serial node red, with MatLab work perfectly, but I wanted to send the data to the Dashboard.
In Python works with PyVisa.
