Neither NI-VISA Interactive Control nor pyvisa can see this device, but they are able to see other devices that I have connected. It may also be relevant that NIMAX cannot see any of the devices, but if I manually add the RS232 device it can see it and communicate with it until I restart the software. Then, it cannot communicate again.
The SCPI Status Model has a number of registers which indicate instrument status, operations and events. These registers can be queried through a number of commands and return a single number, usually representative of an 8-bit unsigned or 16-bit unsigned integer. The registers values are bit-mapped, which means that each bit represents a ...
And according to the guide, the commans for GPIB are the same for RS232. Honestly I'm new with Python, I would appreciate a little help sharing information to make it work (examples, tips, etc.). python-3.x serial-port pyvisa

RS232 Quick Guide TIA/EIA-232-F Standard RS232 conveys data over a simple unterminated, multiconductor cable at rates up to 20kB. The RS232 standard specifies the electrical characteristics and connector for an all encompassing point-to-point modem interface. Although the original specification was intended for modems, subsequent
PyVISA is a Python package that enables you to control all kinds of measurement devices independently of the interface (e.g. GPIB, RS232, USB, Ethernet). As an example, reading self-identification from a Keithley Multimeter with GPIB number 12 is as easy as three lines of Python code: >>> import vis...
The PyVisa library is a little obscure as to what default termchars are in use by the different subclasses (e.g. SerialInstrument ). If you can write to an instrument but cannot read from it, it is likely that your defined read_termination character isn't correct. Here's an example setting up my instrument whose the termination character is \r.
