Setting up SHED and SHED-6
The SHED-BS and SHED-C do not require an external electrical power supply of any kind.
The only exception is SHED-C for the Panasonic 3800 camera, which requires an external
power supply. 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-BS and SHED-C 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-
BS and between the camera and the SHED-C to maintain optimum performance.
SHEDs can be positioned directly at an access panel ( Figure 2-4 ) or rack mounted with
Grass Valley’s SHED-6, a 1-RU frame that houses six individual SHED-BS units in one simple
enclosure (
Figure 2-5 ).
Note that the SHED-6 requires 12VDC via a 4-pin XLR-M connector. Please also note that
SHED-6 only supports listed Sony and Ikegami cameras.
