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 RS-422 powerline cable LDK 8121/02, LDK 8120/10, LDK8120/25 Headset dynamic XLR-5 with double muff LDK 8111/37 DC power supply 100W 2-out LDK 5901/00 Local Control Panel LCP 100 LDK 5201 Operational Control Panel OCP 400 LDK 4640/10

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 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.

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)

1.5 Int e rcom
An intercom channel connects the base unit to the camera operator's headset. The operator's intercom microphone signal is sent to the base unit. The headset can be connected to the 5 pin XLR headset connector at the back of the DigiLink adapter. For the connector and detailed pin descriptions refer to chapter 2.7.6.
A conversation is started when the camera operator presses the VTR Start button at the front of the camera or the VTR button on the lens. The function and behaviour of this button can be defined in the
INSTALL menu of the camera. Refer to the camera’s user’s
guide.
The volume of the headset earmuffs can be adjusted by turning the audio volume knob at the front (right side) of the camera.
Intercom configuration
The sidetone volume level (feedback signal from the microphone to the earmuffs) can be adjusted withthe
INSTALL/INTERCOM/SIDETONE function n the camera (available only
when a 4-wire connection is used).
Depending on the type of microphone the following items can be set in the
INSTALL/
INTERCOM
menu in the camera:
Microphone gain level (0 or +40 dB) with the CAM.MIC_GAIN function;
Microphone power can be switched on or off with the CAM.MIC_POWER function.
Both 2-wire and 4-wire intercom connections can be used. On the base unit, set the setup switch S1 in the Off-position when a 4-wire connection is used and set it in the On-position when a 2-wire connection is used. Refer to chapter 3.6.1 for the description of the setup switch.
The following figure gives an overview of the routing of the intercom. For the connector and detailed pin descriptions refer to chapter 3.5.
