Chapter 1
DigiLink system
1.1 Introduction
The DigiLink system consists of an LDK 5481 camera adapter and an LDK 4700 base unit for
use with Grass Valley standard definition (SDTV) 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 Grass Valley cameras
in many environments. Depending on the application and cable lengths needed, the system
can utilize low-cost coax cables, existing multicore cables or hybrid or dual fiber connections.
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.

1.3 Compatibility
If you wish to control your camera locally, you can connect an OCP 400 to the RS-232
connector of the camera. When an OCP 400 panel is used with the DigiLink system, C2IP
functions (e.g. file management) are not supported by the system.
Note
☞
The LDK 5481 adapter is backwards compatible with existing LDK 5480 breakout boxes and
can be connected to them as described in the LDK 5480 User’s Guide.
1.4 Configurations
1.4.1 Digilink system SDI coax configuration
A camera head with an LDK 5481/00 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).

1.4.4 Stand alone multicore configuration
A camera head with an LDK 5481/00 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 5 m (17 ft) when the component outputs are used in the recorder.
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 100 m (330 ft). With minimum power supplied from the
recorder unit the maximum length is 25 m (80 ft).

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.)
