Chapter 1
DigiLink system
1.1 Introduction
The DigiLink system consists of a camera adapter (LDK 5481) and a base unit (LDK 4700) for
use with Grass Valley standard definition (SD) camera heads. The system features digital signal
processing and digital transmission of all signals between the camera head and base unit to
ensure there is no loss of quality.
As well as delivering high-quality 10-bit SDI video and audio of CD quality, the bidirectional
digital transmission system carries teleprompter, external video for viewfinder, intercom,
control and tally signals, embedded genlock and private data signals. All these signals are
embedded in the SDI signal streams.
The flexible system configuration makes DigiLink the ideal companion for LDK cameras in
many environments. Depending on the application and cable lengths needed, the system can
utilize low-cost coax cables or existing multicore cables.
Typical applications for DigiLink include educational use or small studios such as local TV
stations, continuity or announcement studios. It is also ideal for use in conference and
parliamentary systems or in high-end surveillance. The camera with DigiLink adapter can also
operate as a stand-alone unit by using its VTR output.
1.2 Accessories
The following DigiLink accessories are available:
RS-232 powerline cable LDK 8120/02, LDK 8120/10, LDK8120/25

1.4 Configurations
1.4.1 Digilink system SDI coax configuration
A camera head with an LDK 5481 adapter can be connected to the LDK 4700/00 base unit
using two coax SDI cables. The maximum length of cable that can be used is 250m (820 ft).
High quality coax cable should be used (for example, Belden 1694A). The DC power supply
for the camera is supplied directly to the adapter by an optional local power supply or by the
base unit (using a DC power cable).
Figure 1-1. DigiLink system SDI coax connection
When a DC power cable is used to power the camera from the base unit, refer to section 6 for
the pin layout of the DC connectors. The maximum length of the cable depends on the type of
cable and the power used by the camera. The table below is an indication of the cable lengths
that can be used.
Table 1-2. cable length indication for DC power cable
☞Note
Always use a power cable from the portable power cables category, type W, G, G-GC or PPE.
The cable should be listed in accordance with NEC article 400 of ANSI/NFPA70.

1.4.2 DigiLink system multicore configuration
A camera head with an LDK 5481 adapter can be connected to the LDK 4700/10 base unit
using multicore cable. The maximum length of cable that can be used is 75m (250 ft). The
base unit can supply power for the camera via the multicore cable. The power consumption
of the camera may reduce the maximum length of cable that can be used, so alternatively, the
power for the camera can be supplied directly to the adapter from the optional LDK 5901
power supply.
☞Note
Always use a listed 26-pin CCZ-A multicore cable compliant with EBU N21 (for example, Draka
multicore camera cable type 755-2 PVC.)
Figure 1-3. DigiLink system multicore connection
1.4.3 Stand alone SDI coax configuration
A camera head with an LDK 5481 adapter can be connected to a recorder unit using an SDI
coax cable. Only the SDI signal is passed via the coax cable. The maximum length of cable that
can be used is 300m (1000 ft). High quality coax cable should be used (for example, Belden
1694A). The DC power supply for the camera is supplied directly to the adapter. The LCP 100
can be connected directly to the camera.

Figure 1-4. Stand alone SDI coax configuration
1.4.4 Stand alone multicore configuration
A camera head with an LDK 5481 adapter can be connected to a recorder using a multicore
cable. Power can be supplied by the recorder via the multicore cable or directly to the adapter
itself. To avoid degradation in the video signal, the maximum cable length is restricted to 5m
(17 ft.) when the component outputs are used in the recorder. The LCP 100 can be connected
directly to the camera.
If the recorder uses the SDI signals, then the maximum length of cable depends on the ability
of the recorder unit to supply sufficient power to the camera. When the adapter is powered
directly the maximum length is 100m (330ft). With minimum power supplied from the recorder
unit the maximum length is 25m (80ft).
☞Note
Always use a listed 26-pin CCZ-A multicore cable compliant with EBU N21 (for example, Draka
multicore camera cable type 755-2 PVC)

2.3 Compatibility
Before using the LDK 5481 DigiLink adapter you must ensure that it is compatible with your
camera head. Camera heads with software version v13.0 and higher are fully compatible and
do not need to be upgraded. Camera heads with software below this version must be
updated.
Older camera heads with data board no. 3922 406 84271 or LDK 100 cameras built before
2001 need to be upgraded. For more information on upgrading your camera contact your Grass
Valley service representative.

the multicore connector or via the DC IN socket. Set the power source selection switch (1) to
the position that corresponds to your chosen method:
• LOC: Powered via DC IN socket
• REM:Powered via multicore
The power on indicator (2) lights when power is supplied and the camera power switch is On.

LDK 5481 + LDK 4700 User’s Guide | LDK 5481 DigiLink Adapter 2-6
If excessive current flows in the camera or adapter, the circuit breaker (4) 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.
2.5 Attaching the LDK 5481 adapter to a camera head
The LDK 5481 adapter is shorter than a standard adapter. Before attaching the LDK 5481
adapter to a camera, the carrying handle must be re-positioned on the camera head using the
mounting bracket supplied with the adapter.
To re-position the carrying handle for a short adapter, proceed as follows:
1. Remove the viewfinder and any other adapter attached to the camera.
2. Unscrew and remove the two screws that attach the front of the carrying handle to the
camera. (For the LDK 500: tilt the carrying handle backwards and use your fingertips to
gently unplug the flat cable that connects the zoom control to the connector inside the
camera body.)
☞Note
The digital zoom control of the LDK 500 cannot be used in combination with the LDK 5481
adapter. An optional analogue zoom control LDK 6113 can be used.
3. Remove the carrying handle from the camera.
4. Use the supplied screws and washers to attach the mounting bracket to the top of the
camera. (Use the screw holes where the handle was previously attached.)
Figure 2-1. Carrying handle replacement
5. For LDK 500: fold the flat cable away into the hollow part of the carrying handle.
6. Place the carrying handle into the recess at the front of the mounting plate and use the
two original screws to secure it in place.
7. Attach the LDK 5481 adapter to the camera (refer to section “Attaching an adapter” in the
User’s Guide of your camera for further instructions).
