2.2 Installation requirements for the D2 digitizer

Requirements

• The D2 digitizer should not be placed in a built-in installation or enclosure unless proper ventilation is provided.

• When using the unit in a multi unit rack assembly or closed assembly, the ambient temperature inside the assembly may not

exceed the maximum rated ambient temperature of the digitizer. The installation should be such that the amount of air flow

required for safe operation of the equipment is not compromised.

• When building in the D2 digitizer into a rack with cover door, be aware that a space of minimum 85 mm is needed between the

indicated reference and the cover door. This space is needed to guide the input cables to the inputs.

85 mm

• The D2 digitizer will require that air flows freely in vent holes. Blocking these holes will greatly reduce the reliability of the unit

and lead to the possibility of overheating.

• The D2 Digitizer should operate from an AC power source. The D2 digitizer is equipped with an auto-ranging power supply

from 85 to 264 volt (50–60 Hertz).

• When installed in a rack, the mounting should be such that no hazardous condition is achieved due to uneven mechanical

loading.

• When the mains switch located on the back of the D2 digitizer is not accessible due to rack mounting, the socket outlet supplying

the rack shall be installed near the equipment and be easily acces

sible or a readily accessible disconnect device shall be

incorporated in the fixed wiring. When using a rack in an installation it is advisable to log the serial number of the device and to

activate the warranty figure by registering utilizing the included form.

• Do not place the D2 digitizer on an unstable cart, stand or table. The device may fall, causing personal injury and serious

damage to the digitizer.

• The data path between the D2 digitizer and the LD display may not exceed five (5) meter.

3. System overview

3.1 LD display tiles

Functionality

The display of the LD is built up with display tiles. All tiles are connected in series via a data path. The physical location of a tile in the

data path does not matter because within the LD model all tiles are equal. But the data path must be created in a daisy chain matter.

Each tile picks out a part of the video information of the data stream on the data path and process this information for displaying on

its LED’s.

Depending of the chosen LD model the resolution of the display tile can be different, either 8 millimeter or 10 millimeter. The LD tiles

need to be powered up via the mono phase power box which supplies a voltage between 190 and 230 volt.

Image 3-2

LD display tile (8 millimeter: R9052700 ; 10 millimeter: R9052710).

Re-sync unit

Every tile contains a re-sync unit (A) which can easily be removed. The re-sync unit synchronizes the incoming data stream and

sends it to the next tile. The data ports (B) on the re-sync unit are bidirectional. So, it doesn’t matter on which port the data is coming

in, the re-sync unit switch the functionality of the data ports spontaneously between input and output. Furthermore the re-sync unit

is equipped with status LED’s (C) for diagnostic purposes.

Cabling

The display tile is provided with power via a power split cable with a C13 plug. Data cabling between tiles is done with a DVI-DVI

data cable of 0,9 meter.
