Reliable PCI(e) RS232 Card

[Dan Bookwalter N8DCJ]

I may be in need of a dedicated serial adapter , the NI ones are super expensive , but , if it was up to me thats what I would buy...

So , does anyone have any recommendations .... you can find them anywhere from $20 to $600

obviously it needs to interface with NI-MAX , although I am sure they all would..

I am personally a fan of StarTech.  I have not used their PCIe adapters, but their USB-RS232 adapters are really good.

As far as working with MAX, they just need to be normal COM serial ports and VISA will do the rest.

Is PCIe a requirement? FTDI (assuming you get them from reliable sources) produce very reliable USB to RS232 cables. They also have TTL and LVTTL versions.

As another alternative, I am always a fan of Brainboxes ethernet to serial adapters. Can be installed as a COM port on Windows machines or can act as a TCP gateway to avoid having to deal with COM ports at all.
