Device is Occupied

Multiple instances of LightField can be running at the same time.

However, a device currently being used by one instance of LightField

will be shown in the Available Devices area as "Occupied" for all

other instances of LightField. To make a device available to the current

instance of LightField, either remove it from the Experiment Devices

area in the other instance or close the instance that is using the device.

This message may appear if the PVCAM.INI file has become corrupted or if the camera

was not turned on before you started WinView and began running the Camera Detection

Wizard. If one of these dialogs pops up:

1. See "Controller Is Not Responding," page 66.

2. Run the Camera Detection Wizard.

If an external shutter is being used, check to see that the shutter is opening and closing

correctly. Possible shutter problems include complete failure, in which the shutter no

longer operates at all: the shutter may stick or open (causing overexposed or smeared

images) or stick closed (resulting in no images). It may even happen that one leaf of the

shutter will break and no longer actuate. High repetition rates and short exposure times

will rapidly increase the number of shutter cycles and hasten the time when the shutter

will have to be replaced.



Cancel the load. Cancelling 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.
