USB capabilities with Labview

[jgr5]

Hello,

Our group has developed a system that connects to a PC via an RS232 (as well as parallel) port. In general, the system receives ultrasound pulses and notifies the computer, which then keeps track of the time in between pulses and displays the results to the screen. This process is currently done through an application we developed ourselves, but we would like to upgrade both our hardware and software, and thus Labview appears to be our likely path. My question is, what is involved in changing the hardware and software of our system? Does this seem like a feasible approach if we use the NI RS232-USB adapter and Labview, as well as (I am assuming) the NI-VISA API?

Any advice or suggestions would be greatly appreciated.

Both NI USB-232 units (the cables and boxes) appear as a standard COM port which is accessible through VISA in LabVIEW via the NI-VISA API. Since your application uses a standard RS-232 port, this should solve the serial-side of your problem. In fact quite a bit of our serial test software is written using VISA and LabVIEW, so this is a well-tested path.
