usb to rs485 converter

[mikelandry]

I need to know if the NI USB to RS 485 converter has the ability to configure individual ports for 2 wire and or 4 wire operation independantly?

Yes! The USB-485 ports are all individually controlled, so you can configure each one either through the device manager or by making an IOCTL call from software. Everything is independant.

is there a speed increase with going to USB from RS-232? or is it pretty
much defined by the device you're connecting to?

Are you referring to connecting directly to USB capable equipment? Or connecting to RS-232 capable equipment using a USB-232 convertor?
