Hi,
We have these Vacon NXS-series VFDs and want to monitor and control them using a PC. The drives come with rs-232c ports and I'm wondering if I can expect things to work out with some kind of a multiport usb-to-RS232 adapter (for example https://www.serialgear.com/4-Port-Serial-USB-USBG-4X232P1-10.html).
I understood that RS-232 can be used only to communicate between two devices. This USB-adapter then would create virtual COM ports. Are there any obvious reasons why this might not be a good solution?
The option is to buy some extension cards which there are available for various different buses. But they seem a bit costly and possibly difficult to acquire.
