Chapter 3 First Light 29
Getting Started
1. If the system cables haven’t as yet been installed, connect them as follows (system
power off). See Figure 7.
• Connect the 25-pin cable from the DETECTOR connector on the
Analog/Control module panel to the mating connector at the camera. Be sure to
secure the cable at both ends.
• Connect one end of the interface cable to the SERIAL COM or USB 2.0 connector
on the Interface Control module panel. Connect the other end to the computer
interface as described in Appendix I. Be sure to secure both ends of the cable.
• Connect the line cord from the Power Input assembly on the back of the
controller to a suitable source of AC power.
2. Mount a test target in front of the camera.
3. If you haven’t already done so, install a lens on the camera or connect it to your
microscope or other system optics, whichever applies. See the manual for your
particular camera. The initial lens settings aren’t important but it may prove
convenient to set the focus to approximately the anticipated distance and to begin
with a small aperture setting.

4. If the TE-cooled camera requires coolant, connect a source of liquid coolant. For
purposes of these checks, ordinary tap water will be fine. Liquid cooling may be
necessary with TE cameras (some CCDs, such as the SITe 512x512, don’t operate
correctly unless cooled to approximately -40°C.) With liquid cooling you will be able
to cool TE cameras to -50°C. Without liquid cooling, a TE camera can only lock to
-5°C, unless it is a model having forced air cooling, in which case temperature lock
down to -40°C (-90°C for the XTE) can be achieved.
5. Turn on the controller power.
Notes:
1. A camera overload alarm may sound briefly and then stop. This is normal and is
not a cause for concern. However, if the alarm sounds continuously, even with no
light entering the camera, something is wrong. Turn off the power and contact
the factory for guidance.
