When LabVIEW is targeted, Instrument I/O Assistant will enumerate the
list of local resources--not the remote resources. When you run the
I/O Assistant task that you have configured and parse your data, it
will send and recieve data with the local resource, even though
LabVIEW is targeted. When the VI containing the express block VI is
downloaded to the target and executing, it will use the same resource
name specified in the I/O Assistant but will try to connect to the
remote resource name - in this case I assume it is ASRL::1::INSTR
(COM1) or some other serial port. I assume you are connecting your
instrument to the serial port on your local host when running the I/O
Assistant, and then connecting the instrument to the corresponding
serial port on your target
when running the VI on the target. You may
want to confirm that the serial settings on the two com ports are the
same; if the settings for your local com port are correct, but the
remote com port settings are different, then this would cause the I/O
Assistant to work with the serial port locally but the VISA calls to
timeout remotely.
Hope this helps
