conductor to insure adequate voltage without excessive drop. Using #10
wire, a separation of 200 feet is possible and this assumes an approxi-
mate voltage drop of 20%0. Therefore, for an output voltage of 18 volts
the voltage from the power supply is 22 volts. The power supply will be
powered by 220 or 110 volts AC, selectable at the supply. If central
power distribution from the control area is necessary the supply will
be through 1900 feet of environmental protected, #12 AWG cable, supplied
in 3 pieces (see cable section).
3. Standard Cameras
The Standard Camera chain is interconnected as depicted in Figure 2.
The camera head, preamp, control unit and sync generator are all con-
tained within one compact enclosure. The camera head provides a
standard 16 mm "C" mount for acceptance of zoom or fixed lens. Zoom
electrical connections are routed directly into the camera head. One
composite video output of up to 3 volts p-p is available for distribution
to either microwave transmitter, or monitor. Another output is avail-
able for remote control of lens, target, beam, focus, pan/tilt, and other
important camera set-up functions at a location up to 2000 feet from the
camera by use of environmental resistant 23 conductor camera cable.
The pan/tilt and lens control lines are routed through the Camera Unit.
4. Three-Dimensional Configuration
When the 3D configuration is utilized, radiation tolerant camera
heads #1 and #2 or #1 and #3 are combined on the 3D mounting accessory
(Figure 3). Except for the sync generator, no common electrical connection
exists between the two camera chains, only the appropriate mechanical
mounts and viewing mirror. See Appendix D for further discussion of
3D equipment (for Range Finder discussion see Section IV, H4).-61-
