1 Important information

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! Don’t 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.

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.
External signal selection
The External signal selection switch (9) selects either the EXT1 or EXT 2 signal from the Base Station.
In addition to this switch, other switches on the camera (VTR start) can be set up in the Install menu to switch this function.
Output monitoring signal
The monitoring output selection switch (10) determines whether the viewfinder signal from the camera or the external video signal from the Base Station is available at the output connector

3.3 Using audio

Two high quality audio channels are available in the fibre mode. Set the gain levels (-22 to -64 dB) for these channels in the Audio section of the Install menu. A high-pass filter for each channel can also be switched on via this menu.
.
HD Fibre adapter LDK 5476 | HD Fibre adapter controls 7
Audio channel 1
The microphone for channel 1 is connected either to the socket at the front-right of the camera or to the Mic 1 socket on the adapter. A 3-position switch (5) activates the socket at the front-right or the connector at the rear. The third position selects the rear socket with a phantom power supply (48V).
Audio channel 2
The microphone for the second audio channel is connected to the Mic 2 socket on the adapter. A 2-position switch (8) selects a phantom power supply (48V) for the second audio microphone.

3.4 Intercom

Three intercom channels – production (Prod), program sound (Prog) and engineering (Eng) – are sent from the Base Station to the camera operator's headset. The camera operator's intercom microphone signal is sent to the Base Station. A tracker can also connect a headset to the intercom system to receive all of the channels from the Base Station and the camera operator's microphone signal as well. The tracker's microphone signal is passed to the camera operator and to the Base Station.
The Intercom section of the Install menu contains various settings for all these channels. Signals for left and right headset muffs and sidetone levels can be selected. Intercom microphone amplification levels, phantom power supply and microphone on/ off switches are also available in this menu.
Additional controls are found on the back of the adapter.
Intercom microphone routing switch
This 3-position switch (1) routes the camera operator's intercom microphone signal to engineering (Eng) or production (Prod), or turns off the intercom. Use the VTR Start button at the front of the camera, or the VTR button on the lens, to send the camera operator's intercom microphone signal to production, regardless of the position of this switch.
Production volume control selection
Use this 2-position switch (2) to control the volume of the production signal in the intercom either at the front of the camera
or at the rear of the adapter.
Intercom headset volume controls
• Prod - adjusts the volume of the production signal to the camera operator's headset when selection switch (2) is in the REAR position.
• Prog - adjusts the volume of the programme signal to the camera operator's headset.
• Eng - adjusts the volume of the engineering intercom signal to the camera operator's headset.

3.5 Communication

Call button
Press this momentary button (4) to send a signal to the control panels calling for attention. The ND/RE indicator in the 1.5-inch viewfinder shows when a call signal is sent or received.
Data channel
The Aux connector on the side of the adapter provides analogue control signals and facilities for the connection of a two-way private data channel between camera and Base Station. In the Install menu, the tracker microphone and engineering intercom channels can be selected to carry the private data instead of their normal function.
On-air signal
The tracker connector on the side of the adapter, as well as providing full intercom facilities for the dolly or crane driver, also carries a tally signal and a +12 Vdc power supply. This allows an external on-air lamp to be used.
