5.1 System On/Off Sequences
If your system is configured for the USB 2.0 communication interface, you must follow
the system on/off sequences as stated below. These sequences ensure that
communication is established and maintained between the camera and the host
computer:
The PI-MTE camera must be powered on before WinView/32 is opened to ensure
communication between the camera and the computer. If WinView is opened and the
PI-MTE is not powered on, many of the functions will be disabled and you will only be
able to retrieve and examine previously acquired and stored data. You must close
WinView, power the camera on, and reopen WinView before you can set up
experiments and acquire new data.
WinView/32 must be closed before powering the camera off. If you power the camera
off before closing WinView, the communication link with the camera will be broken.
You can operate the program in a playback mode (i.e., examine previously acquired
data,) but will be unable to acquire new data until you have closed WinView, powered
the camera on, and then relaunch WinView.
5.2 First Light
This section provides step-by-step instructions for acquiring an imaging measurement
outside of a vacuum environment (the visible nose is installed on the camera). The
intention of this procedure is to help you gain basic familiarity with the operation of
your system and to show that it is functioning properly before removing the visible nose
and installing the camera in a vacuum environment. Once basic familiarity has been
established, then operation with other operating configurations, ones with more
complex timing modes, can be performed.
Information in this section assumes that:
1. The camera has the visible nose installed (the camera is shipped with this nose) and
that you are verifying the camera system operation.
2. You have read Chapter 4, System Setup , and the previous sections of this chapter.
3. You have made the appropriate cabling and coolant connections for your system.
4. The system is liquid-cooled.
5. You are familiar with the application software.
6. The system is being operated in imaging mode.
7. The target is a sharp image, text, or a drawing that can be used to verify that the
camera is seeing and can be used to maximize focus.
