E.5 Device Is Not Found
When LightField is launched, it looks for devices (e.g., cameras, spectrographs, and
filters,) that are powered on and connected via a communications interface with the
host computer. If it cannot find a device that had been used in the last experiment, it
will continue to look for it.
Figure E-1 illustrates a typical error dialog displayed when LightField is unable to locate
a device (e.g., a spectrograph.)

When trying to determine the cause for the hardware’s not being found,
• Verify the device is connected and powered on.
— If LightField cannot find a spectrograph that is connected and powered on,
turn the spectrograph off and back on. LightField should now find it.
• Cancel loading the experiment.
Canceling a load means that the last used experiment will not be loaded
automatically when LightField opens. However, you can load the experiment
after all the devices are available, you can start a new experiment design, or you
can load a different experiment that matches the devices you are using.
E.6 TEC Fault LED Comes On
When cycling the power supply off and on, wait a minimum of 10 seconds before
switching the supply back on. The TEC Fault LED may come on if the power supply’s
on/off state is switched too quickly.
NOTE:
The TEC Fault LED will also be illuminated if there is a
problem with the cooling system.
