Setting up SHED and SHED-6
The SHED and HDX-BS and the SHED and HDX-C do not require an external electrical power
supply of any kind. What little power they do consume is provided by the camera system. In
a passive system, only the fiber link of two singlemode ST terminated fibers needs to be
provided. As the camera head is locally powered, the SHED and HDXs merely serve to "fool"
the camera and base station into believing there is a piece of SMPTE hybrid cable between
them.
SMPTE Hybrid cable lengths should be as short as possible between the CCU and the SHED
and HDX-BS and between the Camera and the SHED and HDX-C to maintain optimum
performance.
SHED and HDXs can be positioned directly at an access panel ( Figure 2-4 ) or rack mounted
with our SHED and HDX-6, 1 RU frame that houses six individual SHED and HDXs in one
simple enclosure (
Figure 2-5 ).
Note that the SHED and HDX-6 requires 12VDC via a 4-pin XLR-M connector. All SHED and
HDXs come standard with the LEMO SMPTE connector and Fischer can be provided on a
special order basis.
