SHED and HDX Features
System Operation
System Operation
Since the HDX does the job of actually powering the camera head, the majority of its
purpose is to produce the high voltages required by today's HD camera and large zoom
lens systems. The remaining purpose is to sense the type of camera system that is attached,
either Sony or Ikegami, and then proceed through the proper start-up sequence that safely
provides the appropriate voltages.
Since the optical portions of SHEDs and HDX's system are passive, the maximum distances
that can be achieved are determined by the optics in your camera system. As most HD
camera systems on the market today have optical budgets of around 12-14db, it is
reasonable to assume that with ideal fiber and minimal connector losses, theoretical
distances of 20km can be realized. Single mode fiber is mandatory.
Once powered up, the HDX will attempt to recognize what it is attached to. It is designed to
work with:
• Sony 750 and 950 HD Camera systems
• Ikegami HD Camera systems
• Power Plus (see Copperhead manual for details)
See
on page 14 for an actual list of compatible Sony And
Ikegami Camera systems.
Use of the HDX with any other equipment will result with an error condition indicated by
ERR on the HDX 4-segment display. As long as an error condition is detected, no high
voltage will be enabled.
