1.1 Fibre optic transmission units
CLASS 1
LASER PRODUCT
LASER KLASSE 1
PRODUKT
The CLASS 1 LASER PRODUCT label is located on top of the fibre optic connector on
the rear panel.
Laser safety statement (Europe)
Fibre optic transmission units are classified as a "CLASS 1 Laser Product" according to
EN 60825-1, Safety of Laser products. Class 1 laser products are considered safe and
do not result in biological hazard if used according to the instructions.
Laser safety statement (US)
Fibre optic transmission units are classified as a "CLASS 1 Laser Product" according to
21CFR 1040.10 of the US Food and Drug Administration (FDA) Center for Devices and
Radiological Health.
WARNING
Use of controls, adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.


To ensure proper use of this product, please read this instruction manual carefully and
retain for future reference. Should the unit ever require maintenance, contact an
authorized service location.
1.2 Handling precautions
A number of events can damage fibre optic connectors and cables. Unprotected
connector ends can experience damage by impact, airborne dust particles, or excess
humidity or moisture. To prevent deterioration of performance observe the following:
Always put the dust caps on cable and panel connectors immediately after
disconnecting a cable.
Keep connectors and dust caps clean.
Never touch the fibre end face of the connector.
Do not overly bend the cable where it attaches to the base of the connector.
Avoid applying tension to the cable. HD Fibre adapter LDK 5476 | Important information
3
Do not twist the cable.
Insert the cable straight into the connector, not at an angle.
Do not allow the cable to kink.
Avoid impact damage to connectors; do not let them hit the floor.
Cover a fibre optic connector when it is not in use.
Cleaning
The fibre end face and ferrule must be absolutely clean before it is inserted into a
transmitter or receiver. Dust, lint, oil (from touching the fibre end face), or other
foreign particles obscure the end face, compromising the integrity of the optical signal
being sent over the fibre.
WARNING
Never clean an optical connector attached to a fibre that is carrying light.
Fibre optic connectors need to be cleaned every time they are mated; it is essential that
users develop the necessary discipline to always clean the connectors before they are
mated. Mate the connector immediately after cleaning! Dont let the connector lie
around and collect dust before mating.
The connectors used on the LDK 5476 HD Fibre adapter and LDK 4503 Base Station
are Lemo hybrid optical connectors (SMPTE 304M). Refer to the connector
manufacturer for specific instructions on cleaning these connectors. HD Fibre adapter LDK 5476 | Specifications

3.1 Powering the camera
The power supply for the camera and adapter is normally supplied via the fibre cable
from the Base Station. The power on indicator (6) lights when power is supplied and
the camera power switch is On.
When power is supplied via the fibre cable, an output power socket supplies +12 Vdc,
1.5A maximum for powering accessories.
If excessive current flows in the camera or adapter, the circuit breaker (7) trips and
shuts off power to all the units. If this happens check the units for faults and if
necessary take corrective action before pressing the circuit breaker button to reset the
power.
It is also possible to operate the camera without a fibre cable by supplying a +12 Vdc
supply to the DC input socket.
3.2 Selecting monitoring signals
Viewfinder display signal
The viewfinder can display local or external video signals. Two switches (11) determine
the signal that is displayed in the viewfinder.
Set the first switch to LOC to display the local camera Y signal in the viewfinder. (The
Ret. button on the lens also selects this signal in parallel with this switch.) If set to the
other position, then the second switch determines the signal displayed in the
viewfinder.
The second switch selects the signal displayed in the viewfinder when the viewfinder
signal selection switch is not in the LOC position. The signal then displayed is:
EXT
Base Station external input 1 or 2.
MIX
Base Station external input 1 or 2 and camera Y signal mixed.
