Hello,
I have a question regarding serial communication: is it possible to directly hook a device via RS232 serial to digital pins of a USB-6211 DAQ? (Or maybe even a USB-6008?)
If so, where should I wire the pins to?
If not, could you recommend me a not too expensive, yet functional RS232 to USB adapter which could work fine? (I am planning to interface a Datex capnometer or a Fresenius Pilot C infusion pump first, however if I could find a relatively well-priced multi-port adapter I would go on with both. BTW, can I include more NI-VISA queries in parallel in LabVIEW?)
Thanks

Okay, then I should proceed with the adapters. With these I had a bit difficulty: I find plenty of devices which support USB to UART RS232 (based on FT232RL and FT232RQ chips), however I guess, that these are not suitable for my needs. Am I right?

The main difficulty is that I am not familiar with these devices. I thought it was not suitable because all the pages say that cables based on these chips are for 3v3 to 5v connections between an arduino and a pc, while there are some more expensive cables which do not mention uart or 3v3 connection.
Should I worry about this or can I go on with these chips?

Okay, thanks 🙂
