Using linx and an error says "Property Node (arg1) in VISA Configure Serial Port (Instr).vi

[kimdh549]

1.Used device

- arduino UNO

 : COM3, currently communicating with CO2 sensor(Baud rate 115200, on Arduino IDE, using certain library functions from GitHub)

- SCD30 CO2 sensor

 : connected to arduino board [SDA, SCL, 5V, GND], device address=0x61, sampling every 2s.

I tried to get digital signal from CO2 sensor (or arduino board) using LINX, LINX I2C blocks. But I got the error I wrote in the title.

here's full error message.

Property Node (arg1) in VISA Configure Serial Port(Instr).vi->LMH-LINX.lvlib:Device.lvlib:Serial Open.vi->LMH-LINX.lvlib:Device.lvlib:Initialize Device.vi->LMH-LINX.lvlib:Initialize.vi->LMH-LINX.lvlib:Open Serial.vi->CO2_test.vi

I'm attaching my VI to get some corrections.

I'm guessing "N/A" is not a valid VISA resource.
