PyVISA Examples

Install required packages:

pip install pyvisa pyserial

to use it as a serial port do:

>>> import pyvisa
>>> rm = pyvisa.ResourceManager()
>>> rm.list_resources()                     # should display the serial port
>>> T = rm.open_resource( given serial )
>>> T.query_ascii_values('meas:temp?')
[26.6016]

or connect to the thermometer remotely, i.e. by using IDM and an option to attach a serial port as a stream, which creates TCP/IP socket listening on localhost port 33100:

>>> import pyvisa
>>> rm = pyvisa.ResourceManager()
>>> T = rm.open_resource("TCPIP::127.0.0.1::33100::SOCKET", read_termination="\r\n")
>>> T.query("*idn?")
'ISOTEL,Precision Thermometer,5C3F1C94,1.0.0-1.0.0.9'
>>> T.query_ascii_values("meas:temp?")
