fieldpoint serial port example

[Swissdude]

Could anyone supply an example app for the use of the serial port on a cFP-2000? The client VI on the host PC should accept ASCII strings and send it to COM1 on the fieldpoint and show the response from the RS232 device attached to it (also in ASCII). Thanks.

I'll add an "I'm looking for this, too!" comment. I have one #^!@! instrument
(a Hach EC30 pH meter) which has no 4-20mA output but has a serial interface
which sprays readings out (sort-of). As I am not yet able to replace this
obsolete thing with a real industrial transmitter yet I am forced to try to
talk to it through a spare COM port on the cFP2020.

I am early in my search of the NI site for hints, so I'll keep looking for
already available help...

There is a LabVIEW code example snippet on the "Serial Quick Reference Guide" (search the NI
site for this string and it pops right up). It employs NI VISA VI's to open and configure the
COM1 port, write and read strings and close the port. I haven't tried it.
