Appendix B Reference Information
B.1.22 What type of Ethernet cable can I use for the static IP
configuration?
The spectrometer can be plugged directly into the instrument controller using
a cross-over, shielded Ethernet cable.
When the spectrometer and instrument controller communicate over a
network, use standard shielded Ethernet cables and IP addresses compatible
with the network. The spectrometer imposes significant traffic on the
network, which can cause packet delays to other users. More importantly,
network traffic from other users can negatively impact the reliability of the
communication between spectrometer and instrument controller.
B.1.23 Can I install additional software on the instrument
controller?
Yes, but with qualifications.
The types of applications that can interfere with the measurement of data are
utility programs, network programs, and those working in the background,
such as virus checkers.
ASD programs, such as RS
3
and Indico, require real-time access to the data
that is being streamed from the FieldSpec spectroradiometer at a high rate of
speed. Programs running in the background can cause packets to be lost.
Microsoft Office, image processing programs, and other software applications
generally do not interfere with ASD programs, particularly if they are not
running and competing for CPU cycles and RAM at the same time that data is
being collected from the FieldSpec spectroradiometer.
B.1.24 Why does the software seem to do unexpected things?
To assure accuracy in the collection and processing of data, the ASD
application software is designed to finish its current operation before moving
on. The FieldSpec spectroradiometer outputs a lot of data at a high rate of
speed for the ASD application software to collect.
In addition, the ASD application software will
stack up your keystroke entries
and execute them later in the order they were received.
It is important that you wait for the collection to finish before entering the
commands to launch another operation. Don’t rush into new operations or into
issuing new commands until you see the results of the current command.
