Hello everyone.
I'm Ivan and I'm working with PXIe-1082 chassis with NI PXIe-8840 controller. PXI has real time operating system: NI Real-Time Phar Lap ETS 13.1. My host computer has NI-VISA and NI-VISA Runtime, PXI has NI-VISA Server and NI-USB passport.
I've 2 different devices of USB-to-COM converter. One of there is ICPCON i-7561 (https://www.icpdas.com/root/product/solutions/industrial_communication/converter/i-7561.html). The device is working as COM port repeater for simplicity.
I've tried to connect this device as follows:
1. Pluged the device into USB port at PXI-8840
2. Opened VISA Interactive Control tool on the host PC and found PXI Instrumental resources.
3. Found my USB device which was determined as USB RAW Resource.
4. Opened VISA Interactive Control tool... and the END.
Any attempts to communicate with the device didn't have results.
So my question is simple. How can I communicate with my device (USB-COM converter ICPCON)?
Some more things which I've tried:
1. If I connect ICPCON device to my host PC, which has Windows 7 OS with driver for ICPCON, the device is determined correctly as COM port.
2. If I connect Tektronix oscillscope to PXI, the oscilloscope is determined as USB Instrument resource. After that, I can communicate with the oscilloscope by VISA Interactive control.
Thanks a lot.
