About SHED and HDX
The SHED and HDX systems enable operation of Hybrid-Cable-equipped High Definition
(HD) cameras using only two singlemode fibers. Since the limiting factor of hybrid cables
are the distances at which they can propagate enough electricity to power the camera, the
SHED and HDX’s eliminate the copper and thus extend the total range of your camera
chain.
The SHED and HDX are optically passive meaning that the optical signals to and from the
camera are merely passed through the system. The electrical signals are interpreted to both
allow the CCU to recognize that a camera is attached and to safely allow the local powering
of the caSHED and HDXmera. ALL audio, video, and data signaling in the camera chain is
maintained.
About SHED and HDX
The SHED and HDX system consists of various parts depending on which versions of the
components were ordered. Since these systems can operate passively using just SHEDs or
actively using a combination of a SHED and an HDX, the components in your order will vary
with your specific application.
Product Returns
In the unlikely event of damage to your SHED and HDX during shipping or delivery, take
note the damage with the delivery or shipping service. If any component does not work
correctly out of the box, contact Grass Valley (see
If the problem cannot be remedied through a service telephone call, an RMA number
(Return of Merchandise Authorization) will be issued. Please note this RMA number inside
and outside of all shipping boxes and on all documentation provided with the items to be
returned.

Setting Up a System
There are two basic ways in which SHED and HDX units can be used to augment your HD
camera systems, and both concern how the camera is ultimately powered.
Passive Set-up - SHED-BS and SHED-C
In a Passive set-up, a SHED-BS is connected to a SHED-C with two singlemode fibers
Figure 2-1). In this configuration, the camera head must be locally powered via a battery or
(
a suitable local power supply.
Installation and Configuration
Fig. 2-1: Passive SHED-SHED System
Active Set-up - SHED-BS and HDX
In an Active configuration, a SHED-BS is connected to an HDX via two singlemode fibers
and the HDX supplies power to the camera through up to 100m of SMPTE Hybrid Cable
Figure 2-2).
(

Page 8
Installation and Configuration
In each case, a SHED-BS returns an electrical signal to the base station that facilitates the
operation of the camera even though there is no physical copper connection. The SHED-BS
requires no external power supply.
Fig. 2-2: Active SHED-HDX System
SHED-BS Configuration for Camera Types
The SHED-BS supports multiple camera types, and each has different interface
requirements at the CCU end. The SHED-BS must be manually configured for the type of
camera in the system, using four DIP switches on the side of the case. A label is mounted on
the case to show the switch positions for the supported cameras.

Sony ON ON ON OFF
Hitachi HD5000 OFF ON ON OFF
Ikegami ON OFF ON OFF
Panasonic 3500 OFF OFF ON OFF
Panasonic 931B ON ON OFF OFF
Panasonic 3800 OFF ON OFF OFF
SHED-C and PANASONIC 3800 Camera
The Panasonic 3800 camera is a special case - the SHED-C is used to feed power to the
camera. A jack on the SHED-C case accepts 12 VDC, and the 10 VDC required for the camera
is fed down the hybrid fiber cable to the camera.

Page 9
Setting Up HDX
The HDX can accept either 120 VAC or 240 VAC. Input voltage selection is NOT automatic; it
must be manually configured by adjusting the Power Entry Module (
The unit accepts AC line voltage with a standard IEC/NEMA type power cord. A window on
the Power Entry Module reflects the current VAC setting, either 115 or 230.
Verify that the voltages on the units are set properly before operating the system.
Changing the Input Voltage
To change the input voltage to the HDX:
1 Use a small, flat-blade screwdriver in the notch at the top of the Power Entry Module to
gently pry open the module cover and expose the fuse block. The cover is hinged at the
bottom and will open easily.
2 Gently pop out the fuse block.
3 Turn the block over and replace it back into the module.
4 Close the module cover.
SHED-C
User Guide
Figure 2-3).
The new input voltage value will be visible in the voltage value window.
The same procedure is followed for fuse replacement. Be careful to replace fuses with ones
of equal voltage, current and duration (3 Amp, 250V, Slo-Blo)
Fig. 2-3: Power Entry Module for HDX
Selecting Normal or Low line voltage range
The HDX operates on AC mains power and can work with a variety of voltages. The internal
power supply can be set for two operating ranges: 120/240 VAC (normal) and 100/200 VAC
(low) +/- 10%, both at 50/60 Hz.
To change between Normal to Low line voltages, it is necessary to open the HDX unit and
change the transformer connections to the Power Entry Module. Proceed as follows:
• Remove all external connections from the HDX.
• Remove the (4) #4-40 screws in the HDX faceplate and carefully withdraw the chassis
from the cover. The connections to the transformer are color-coded and are connected
to the Power Entry Module with 0.187" spade-type connectors ("Fastons"). These are
labeled "A", "B", "C", and "D" on the rear of the power module.

Selecting Normal or Low line voltage range
IMPORTANT
Be sure to remove all external connections from the HDX including the
power cord before attempting these changes.
To convert from Normal to Low voltage operation:
• Remove the Yellow and Black transformer leads from the Power Entry Module.
• Cover these leads with insulation (electrical tape) to prevent contact with the chassis or
other components.
• Connect the unused Blue and Red leads, below. It is imperative that the leads go to the
correct positions or damage to the HDX may result. Re-assemble the HDX in reverse
order to complete the conversion.

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 SHEDBS 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 (
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.

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,
and then proceed through the proper start-up sequence that safely provides the
appropriate voltages.
SHED and HDX Features
Since the optical portions of SHED and HDX systems 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, an HDX with multiple-camera support will attempt to recognize what it
is attached to. The HDX product line is designed to work with:
• Sony 750 and 950 HD Camera systems
• Ikegami HD Camera systems
• Power Plus (see CopperHead manual for details)
• Grass Valley LDK-6000 and -8000 series
• Panasonic 931B, 3500 and 3800
• Hitachi HD1000 andHD5000
See Compatible Camera Systems on page 11 for a complete list of supported 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.

In both active and passive systems, the camera CCU needs to be powered on first and the
camera head needs to be in the ON position. In passive systems, once local power is applied
to the camera, the system should work normally. In active systems, the HDX will take a few
seconds to:
• determine what kind of equipment is attached
• safely apply the correct voltage for that equipment
10
Page 15
LED indicators (see Figure 3-1 and the HDX LED Indicators table above) will show
diagnostic information. An Open or Shorted hybrid cable will always result in a fault
condition. The remainder of the LEDs will be Green or Out depending on what type of
camera (or Power Plus) is attached to the HDX (see the HDX LED Indicators table above).
Incoming optical power is indicated on the lower 4-segment display on the HDX. -20 dBm is
the least amount of optical power that can reliably keep the system functioning. If the CCU
is operating normally (typical optical output of approx. -7 dBm) and the HDX is showing
high loss, check your installed cable for bend radius and connector problems.
The Optional LOCAL/REMOTE switch provides the convenience of having your camera
powered down when optical power to the HDX is turned off. So when the switch is in the
REMOTE position (Faceplate LED = Green), turning your camera CCU Off will also turn
power to the camera head Off.

SHED-C
User Guide
The SHED-C is used in applications where power is applied to the camera locally. The SHEDC can operate in two modes:
•Active - used only with the PANASONIC 3800 camera - power is applied to the camera
from the SHED-C, via a 12VDC external supply connected to the jack on the SHED-C
case. The SHED-C generates the 10 VDC required by the camera, and sends it to the
camera through an SMPTE Hybrid Fiber cable that can be up to 1.5 Km long.
• Passive - used with all other cameras - a local power supply is connected directly to the
camera. The camera is connected to the SHED-C via an SMPTE Hybrid Fiber cable. A
load is placed on the power feed wire used in the active mode.
In both cases, the CCU-end of the fiber run uses a SHED-BS as the Fiber/CCU interface.
The SHED-C is equipped with ST connectors on the fiber-run side, and a LEMO connector
on the camera side, as shown in the figure. Note that other connectors are available as an
option - see
Fiber Connectors on page 8.

The power jack for the 12 VDC supply for active-mode operation with a PANASONIC 3800
camera is located on the side of the case, as shown in the figure.

A Note About Fiber Maintenance
As with any fiber optics system, connector cleanliness is one of the most important factors
leading to a successful implementation. The ST connectors on the various components are
very easy to clean with a "Kim-wipe" and 100% pure isopropyl alcohol. There are a number
of other cleaning methods available.
In terms of cleaning the hybrid connector, there are only two acceptable methods. The first
involves having the proper alcohol swab that can be inserted into the optical cavity without
harming the ceramic alignment sleeve. These are one-time use. The other involves removal
of the alignment sleeve via a special tool made by LEMO and others and then using
conventional cleaning methods once the termini is exposed.
Having a routine maintenance/cleaning schedule for all of your fiber optic gear will provide
you with many years of reliable service.
