Instrument Control (GPIB, Serial, VISA, IVI)
Problem recognizing a serial instrument with a USB adaptor in NIMax
Solved!
Hi Forum,
I have an instrument designed to be controled via serial signal with an RS232 cable and I am trying to get NIMax to recognize it and send some test commands. My laptop (running Windows 7 Enterprise) has no serial port so I am using a USB adaptor to plug it in. When I initially could not get the device to show up, I searched online and found suggestions that I should install the NI-VISA driver. I downloaded and installed it, but it does not help-- the option to open the VISA test panels is grayed out and it says the device is "not present" even when it's plugged in. When I open the VISA interactive control panel directly, the device shows up as a question mark, and if I double click it, it says the following:
Error opening resource:
ASRL10::INSTR
VISA: (Hex 0xBFFF0011) Insufficient location information or the device or resource is not present in the system.
Any thoughts on how I can get my PC to communicate with the device? Thanks in advance for your help.

Does the USB-Serial adapter show up in the Windows Device Manager? Did you install the drivers for the USB-Serial adapter?

You should install whatever Windows drivers are needed for your USB-Serial adapter (should have come with the adapter). Once Windows sees the serial port, so will MAX.
