Cleaning fiber-optic connectors
WARNING
Never clean an optical connector attached to a fiber that is carrying light.
Particles of foreign matter on the tip of a ferrule can have a disabling effect on fiber-optic
transmission. Fiber-optic connectors need to be cleaned every time they are mated and
unmated; it is essential that fiber-optic users develop the necessary discipline to always clean
the connectors before they are mated.
Use a commerially available cleaning kit specifically designed for fiber-optic connectors and
follow the manufacturer's instructions carefully.
• The connector sections to be cleaned include the tips and sides of ferrules, the interior
walls of alignment sleeves, and the interior and exterior of connector shells.
• For plugs, the interior surfaces of alignment sleeves and the tips of ferrules are to be
cleaned with a cleaning stick treated with the appropriate fluid. (Cleaning sticks with a
slender design are available that allow alignment sleeves to be cleaned without having to
detach them.)
• For jacks, it is important to clean both the tips and sides of the completely protruding
ferrules.
• Both the male and female connector shells tend to attract dust and metal particles, so it is
important to clean both the insides and outsides.
• The fiber end face and ferrule must be absolutely clean before it is inserted into a
transmitter or receiver.
• Mate the connector immediately! Don't let the connector lie around and collect dust
before mating.
• Air can be used to remove lint or loose dust from the port of a transmitter or receiver to be
mated with the connector. Never insert any liquid into the ports.

Base Station earthing
The rear of the unit has two separate screw terminals for protective earth (PE) and
video earth (VE). These are normally connected by a metal strap.
The protective earth terminal is internally connected to the protective earth conductor of the
power cable. In normal circumstances the connection between the protective earth and the
video earth should not be broken. If required, the central earth connection wire of the studio
can be connected to terminal PE in accordance with VDE regulation 0800/part2.
Only if the studio (or OB van) is equipped with separate protective and video earth systems
may the metal strap be removed. Under these circumstances the video earth terminal must be
connected to the central functional earth potential (video earth) of the studio. This earth
potential should have functional protective and noiseless earth (FPE) qualities as stated in the
VDE regulation 0800/part2. A low impedance interconnection of both earth conductors must
be provided at the central studio earthing point.
Mains lead wiring for UK users
The wires in the mains lead are coloured in accordance with the following code:
GREEN and YELLOW- EARTH
BLUE- NEUTRAL
BROWN- LIVE
As the colours of the wires in the mains lead of this apparatus may not correspond with the
coloured markings identifying the terminals in your plug proceed as follows:
• The wire coloured GREEN AND YELLOW must be connected to the terminal on the plug
marked with the letter E or by the safety earth symbol or coloured GREEN or GREEN
AND YELLOW.
• The wire coloured BROWN must be connected to the terminal marked with the letter L or
coloured RED.
• The wire coloured BLUE must be connected to the terminal marked with the letter N or
coloured BLACK.
Ensure that your equipment is connected correctly - if you are in any doubt consult a
qualified electrician.

Chapter 1 - Introduction
Chapter 1
Introduction
1.1 Technology
The LDK 4582 HD Fiber Base Station is the perfect interface between your HD camera and the
rest of your system. The heavy-duty base station provides state-of-the-art technology in a
compact package. The high level of modularity guarantees ideal matching with any type of
application; you can use the system in a studio or for mobile field production, for HD or for SD
production.
The Base Station is only 2U high yet offers full broadcast functionality and quality.The low
height means that rack space is saved. Its low power consumption and efficient internal
cooling eliminate the need for space between adjacent units. Sliding rails are additionally
available for easy access to the back panel. The wings on either side of the back panel protect
the connectors from damage, including the hybrid fiber connector. The hybrid fiber connector
itself can easily be mounted at different angles to suit all mounting requirements.
Operational controls
You can access the Base Station menu, which contains all operational settings, from an
Operational Control Panel. In addition to the operational menu, the installation and service
menus can be activated from the Base Station by pressing a switch behind the front panel. The
Base Station is compatible with all existing control system components.
1.1.1 Fiber transmission
The HD fiber system allows video transmission and remote control of cameras up to a distance
of 4,000 m (13,000 ft) and beyond, using industry standard fiber optic cable. It is based on
30 MHz full-bandwidth 4:2:2 transmission (Y/Cr/Cb components). All video and data signals are
transmitted digitally to ensure long cable runs without any loss of quality.

Chapter 1 - Introduction
1.1.2 Modular construction
The modular concept makes it easy to expand the functionality by simply adding new modules.
Quick exchange of the modules for servicing or the ability to swap modules between Base
Stations is another benefit.
External video inputs
The external video input module provides two analog video inputs and loop-through analog
outputs. The signal can be PAL or NTSC, and does not need to be clamped. It can also be non-
synchronized. The external video input module can be replaced in future by a digital one.
High quality SD outputs
Besides standard high-definition outputs, the Base Station can be optionally equipped with
simultaneous high-end SD outputs. This offers ultimate flexibility: produce in SD one day, and
in HD the next, or do both simultaneously. The optional LDK 4530/40 High Quality SD module
adds three 270 Mb/s SDI outputs.
1.1.3 Audio and intercom
The audio and advanced intercom module provides 4-channel intercom, 2-channel digital audio
(AES/EBU compliant) and 2-channel high-quality analog audio from the camera. The audio
channels from the camera head are passed to the different outputs via balanced line drivers on
the module for clean transparent sound. Both analog audio channels are available as digital
outputs on the Base Station. Gain levels can be externally controlled.
In the installation menu of the Base Station, a choice is provided between a 4-wire or a 2-wire
intercom system. A 1kHz test-tone generator and voicemail are available. The voicemail stores
messages from the Program, Production or Engineering channels for the camera operator.
By adding the engineering intercom module, a 5-channel full-featured intercom is possible. The
engineering intercom module provides a 2-channel intercom between camera operator and
engineering. The module fits into the front of the unit and facilitates the plugging in of a
headset and level adjustment for both ear muffs. It is ideal for a simple intercom facility in a
standalone mode of operation, or to expand the 4-channel advanced intercom to a 5-channel
intercom.

1.3 Packing/unpacking
Inspect the shipping container for evidence of damage immediately after receipt. If the
shipping container or cushioning material is damaged, it should be kept until the contents of
the shipment have been checked for completeness and the units have been checked
mechanically and electrically. The shipping container should be placed upright and opened from
the top. Remove the cushioning material and lift out the contents. The contents of the
shipment should be checked against the packing list. If the contents are incomplete, if there is
mechanical damage or defect, or if the units do not perform correctly when unpacked, notify
your sales or service centre within eight days. If the shipping container shows signs of damage
or stress, notify the carrier as well.
If a unit is being returned to for servicing, try to use the containers and materials of the original
packaging. Attach a tag indicating the type of service required, return address, model number,
full serial number and the return number which will be supplied by your service centre. If the
original packing can no longer be used, the following general instructions should be used for
repacking with commercially available materials:
1. Wrap unit in heavy paper or plastic.
2. Use a strong shipping container.
3. Use a layer of shock-absorbing material around all sides of the unit to provide firm
cushioning and prevent movement inside container.
4. Seal shipping container securely.
5. Mark shipping container “FRAGILE” to ensure careful handling.

Installation
2.1 Control bus
The Base Stations are each connected to the control network hub or router via an Ethernet
cable (straight-through, not cross-over). The OCP 400 operational control panels and, if
required the MCP 400 Master Control Panel, are also connected to the Ethernet network via a
hub or router.
An OCP 400 operational control panel can also be connected directly to the Base Station using
a cross-over Ethernet cable.
The IP address and other options for the Ethernet connection can be set up in the Base
Station System menu. These items can also be set up remotely using a network
configuration tool such as Grass Valley’s NetConfig.
☞Note ☞Note
By default the Ethernet connection is set up for automatic IP assignment.
2.2 Power supply
Caution
Connect the Base Station only to a power source with the specified voltage rating. Use only
fuses of the type and rating specified.
The Base Station must always be connected to protective earth. Do not interrupt the
protection conductor inside or outside the unit. Do not disconnect the protective earth
terminal. Intentional interruption is prohibited and is likely to make the unit dangerous.
Before connecting your unit to the power supply check the fuse type (230 VAC or 115 VAC)
on the IEC power connector at the rear of the Base Station.
If the fuse type shown corresponds to your power supply voltage, connect the power supply
for the Base Station to the IEC connector at the rear.

16 LDK 4582 HD Fiber Base Station User’s Guide (v1.0)
Chapter 2 - Installation
If the fuse type does not correspond to your power supply voltage you must change the fuses
before connecting the supply as follows:
1. Insert a small screwdriver into the slot above the pins of the IEC connector and unclip the
fuse holder unit.
2. Insert you finger under the indication unit and pull it out.
3. Rotate the indication unit 180° so that the correct indication for you voltage supply is
displayed at the back of the Base Station (230 or 115).
4. Slide the indication unit securely back into its slot.
5. Insert the appropriate fuses into the alternative fuse holder which is delivered separately
with the Base Station (4 AT fuses are 22 mm long and fit into the 230 fuse holder; 10 AT
fuses are 32 mm long and fit into the 115 fuse holder). The type of fuse holder is marked
on the holder.
6. Slide the fuse holder securly back into the IEC connector until it clips into place.
7. Check again that you have used the correct fuses and that the corresponding indication is
shown.
8. Connect the power supply for the Base Station to the IEC connector at the rear.

2.2.1 Base Station earthing
The rear of the unit has two separate screw terminals for protective earth (PE) and
video earth (VE). These are normally connected by a metal strap.
Figure 2-2. Base Station earthing
The protective earth terminal is internally connected to the protective earth conductor of the
power cable. In normal circumstances the connection between the protective earth and the
video earth should not be broken. If required, the central earth connection wire of the studio
can be connected to terminal PE in accordance with VDE regulation 0800/part2.
Only if the studio (or OB van) is equipped with separate protective and video earth systems
may the metal strap be removed. Under these circumstances the video earth terminal must be
connected to the central functional earth potential (video earth) of the studio. This earth
potential should have functional protective and noiseless earth (FPE) qualities as stated in the
VDE regulation 0800/part2. A low impedance interconnection of both earth conductors must
be provided at the central studio earthing point.
2.3 Connecting the studio intercom system
