Can I use FP-DO-401 to remotely control RS-232 peripheral

[aristotle2497]

I have a function generator I would like to remotely controll in Labview through fieldpoint.  Is this possible to do with a FP-DO-401 unit?  The function generator uses the SCPI programming language for remote control and connects through a RS-232 serial port.  I've looked for information on how to accomplish this task, but I haven't found any definite instructions.

Aristotle2497,

The FP-DO-401 will send out a value as soon as it is written to it, where serial communication requires a baud rate. Because of this, the only way to write data to your function generator with the DO-401 module would be to meticulously write each value within a loop at the correct rate. This may or may not work with a program running with Windows, since it is not deterministic. Also, with the DO-401, you would only be able to send commands, and not receive any.  I would suggest using a FieldPoint controller, which has a serial port on it. This would allow you to directly communicate and use the serial VIs which would be much more efficient.
